customized office chairs

me and my friend need are making a new sport. no b.s.?
its essentially street wakeboarding with customised office chairs and automobiles. (ha ha we know). anyway, we have replaced the wheels of the chairs with some size millimeter skate wheels and thats working well. we’ve hit about 20mph in both of them goin round the neighborhood and looked like idiots doin it but it was fun. we need to find a way to steer it somehow when we’re not being towed.
Drag your feet to steer. Sounds like you are on your way to a Darwin Award. I Like it!
