This town, about ten blocks wide, surrounds a small lake. It's unusual in that everyone lives on one of two streets: either Alameda or Broadway.
All traffic is one-way. Approaching the town from the north, you're on the blue highway labeled North Avenue, which when it reaches the lake curves to the east and becomes Alameda. Starting with address 1000, Alameda circles the lake clockwise. Addresses go up by 100 for each eighth of a revolution. When Alameda crosses North Avenue again, the addresses jump from 1799 to 2000 as the second revolution begins. The addresses reach 5799 before Alameda ends and heads out of town on North Boulevard.
If you turn off Alameda onto any of the radial connectors, you can make another turn onto Broadway, the red line that circles the lake counterclockwise. Broadway begins at 5200, where inbound traffic on blue East Avenue first reaches the town, and spirals inward to end at 1000 Broadway, where it turns into North Boulevard.
The trick in finding a particular address would lie in choosing from among the many opportunities that the radials offer you to turn onto Alameda or Broadway. Get onto one of those streets too soon, and you'd have to circle the whole town one or more times to reach your address. Get onto the street too late, and you'd never find your address because it would be behind you. Directional signs would be important.
