2. No. Although the Indianapolis 500 is one of the world's best-known auto races, its cars are slowpokes by comparison. Go back to 35

3. It's not in any dining guide, but with a mapped length of 348 miles, Kentucky's Mammoth Cave National Park is the most extensive cave system in the world. Back to 7

4. Arizona is proud of its Grand Canyon, the largest land gorge in the world. But the state also boasts being home to some man-made wonders, including the world's most historic "transplant" and longest bar.

(a) True. Go to 11
(b) False. Go to 20

5. Nope, but this is where the most snow fell in 24 hours. On April 14-15, 1921, 76 inches of the white stuff buried Silver Lake. Back to 30

6. No, but lose the wheels and you're close. In 1938 a Class-A stern steerer tore across a frozen Lake Winnebago at 143 mph, setting an ice-yatch world record that remains unbroken. Go back to 35

7. Three different states have a certain subterranean singularity; which state has the edible one?

(a) Kentucky. Go to 3
(b) Texas. Go to 37
(c) Pennsylvania. Go to 14

8. Right! Rising a dizzying 2063 feet above the flat land between Fargo and Grand Forks, the KVLY-TV transmitting tower is the tallest structure on earth. Now flat-out to 35

9. Nope, but close. Pioneer 10 departed from nearby Kennedy Space Center in 1972 and had logged 3.6 billion miles when it departed our solar system in 1983. It's still going. Now you'll have to go to 41

10. Our most populous state, California, has a lot of bragging rights. Which record doesn't it hold?

(a) Oldest living tree. Go to 33
(b) Longest runway. Go to 31
(c) The largest recreational beach. Go to 26

11. Not quite. It's true that London Bridge, the largest antique ever sold, was transplanted to Lake Havasu City in 1971. But the longest bar? Back to 4

12. The 273-foot-tall Louisiana Superdome covers 13 acres, making the New Orleans facility the largest indoor stadium. But it's a pup tent compared with the other two choices. Go back to 15

13. Nope. But a grower in Windham, N.Y., is credited with the world's largest petunia - 13 feet, 8 inches. Go back to 24

14. Bon appetit! Each year Creekside Mushrooms produces 25 million pounds of mushrooms in its 150 miles of underground galleries near Worthington. Now for another tasty treat, head for 24

15. In which state will you find the world's largest building?

(a) Washington. Go to 25
(b) Virginia. Go to 39
(c) Lousiana. Go to 12

16. Biggest grain elevator, yes, but structure, no. Return to 1

17. You get the checkered flag. In 1983 Richard Noble averaged over 633 mph as he tore across the Black Rock Desert in Thrust 2, a car powered by a jet turbine engine. Take off to 4

18. Correct. In 1993 artist Robert Berks used dyed straw to create the image of Will the Great Buffalo. And yes, the big from stem to stern. Mosey on over to 21 for the final leg of or tour

19. Now you're flying. The highest surface wind speed ever measured was 231 mph, recorded on April 12, 1934, at Mt. Washington. Sail on to 10

20. Good choice. Arizona's got the London Bridge, but to beat the desert heat put it to Put-in-Bay, Ohio's Beer Barrel Saloon, and belly up to its 405-foot, 10-inch-long bar. Once refreshed, on to 7

21. You're southbound on Florida's Turnpike and up ahead is the turnoff for Kissimmee, a noteworthy exit, because:

(a) It's the starting point for the world's greatest traveler. Go to 9
(b) It's the starting point for the world's most uncomfortable traveler. Go to 41

22. Wrong, but a vine in Edmond, Okla., did produce a monster tomato weighing a submarine-sinking seven pounds, 12 ounces. Go back to 24

23. Y'all knew this couldn't possibly be the right answer. Now quit dawdling and git on over to 38 where you belong

24. The largest apple ever plucked was from a tree in:

(a) New York. Go to 13
(b) Oklahoma. Go to 22
(c) Michigan. Go to 29
(d) North Carolina. Go to 34

25. Yes (but take a look at 39 before going any further). The Boeing Company's main assembly plant in Everett has a volume in excess of 472 million cubic feet, making it the most capacious building. Next, to 30

26. Right. That honor goes to the well-tanned folks in Virginia Beach, Va., who boast 37 miles of beachfront and more than 11,000 hotel rooms. Now to 27

27. The least populous of all 50 states, Wyoming:

(a) Is first among states in total births. Go to 32
(b) Was home to a half-time-long buffalo. Go to 18

28. Standing 1053 feet above the Arkansas River, the Royal Gorge Bridge in Colorado is the world's highest suspension bridge, but not the tallest structure. Back to 1 and try again

29. Right. At 13 pounds, two ounces, the juicy pride of Caro, Mich., could fill a pie pan all by itself. On to 40

30. Where was the highest wind speed ever recorded?

(a) New Hampshire. Go to 19
(b) South Dakota. Go to 36
(c) Colorado. Go to 5

31. The longest runway in the world is at California's Edwards Air Force Base. It measures 24,582 feet, or 4.7 miles. Back to 10

32. You're not taking this quiz seriously, are you? In 1995, California mothers delivered 564,156 babies - more than Wyoming's entire population, which produced the fewest. Now get on over to 18 and meet Big Will

33. A bristlecone pine growing at 10,000 feet on the California side of the White Mountains is the oldest known living tree on earth. Named Methuselah, it is 4700 years old and is surely the state's most senior resident. Return to 10

34. Wrong. But a gardener in Rocky Mount, N.C., is said to have grown a 62-pound cantaloupe. Go back to 24

35. A manned, wheeled vehicle set the land speed record here.

(a) Indiana. Go to 2
(b) Nevada. Go to 17
(c) Wisconsin. Go to 6

36. Sorry, but you did pick the site of the most extreme temperature change on record. In January 1943, the thermometer in Spearfish rose from minus four degrees Fahrenheit to a balmy 45 degrees in two minutes. Back to 30

37. Not unless you savor bat fillets. But if you do, head for Bracken Cave near San Antonio, because that's where 20 million Mexican free-tailed bats, the world's largest concentration, gather after migration. Otherwise, go back to 7

38. There are no bigger bas-relief images (sculpted on a flat surface) than the 90-foot-high carved Confederate heroes on the face of Stone Mountain outside Atlanta. The mounted figures of Robert E. Lee, Thomas Jonathan "Stonewall" Jackson and Jefferson Davis cover three acres. Like big? Get an eyeful of 15

39. Right (but take a look at 25 before going any further). The largest office building in terms of ground area covered is the Pentagon in Arlington. With a perimeter of 4605 feet, the five-sided, five-story Defense Department headquarters has a floor area of 152.3 acres. Next to 30

40. Is the world's largest bas-relief sculpture in Georgia?

(a) Yes. Go to 38
(b) No. Go to 23

41. Since the next exit is 51.1 miles down the road - the longest distance between controlled-access exits in the country - Kissimmee is probably an excellent place to stop. And so we will. Bye.
