For Travis Pastrana, being a professional freestyle motocross rider is more than just a job, it's a lifestyle. He makes his living performing incredible flips, jumps, and other tricks on his motorcycle -- and, as Nitro Circus shows, he and his friends spend most of their downtime at his compound practicing more of the same. The series wastes little time on the petty bickering and introspective discussions that are so common on other reality shows; it's all action, lots and lots of amazing/outrageous/dangerous action.
