Motorbike stunt riders entertain the public with high flying acrobatics at the annual Republic of Texas biker rally, held every year the week after Memorial Day in Austin, Texas. The two-wheeled aerial acrobats are just one of the many attractions that draw more than 100.000 motorcycle enthusiasts to the ROT-rally. The 20-year old event advertizes itself as: the biggest and baddest biker rally in the Southwest. It is also in the Guinness Book of World Records as having the Largest Biker Parade in the World.
