Skateboarding
One of the most popular extreme sports is skateboarding. This is done on the street or it is done vertically on ramps or "pipes." There are many popular skaters including Tony Hawk, Bam, Bucky Lasek, Bob Burnquist, and Rune Glifburg. You can ask any skater why they have picked that career and all of them would say that it's just for the "thrill."
