the big lump on my tailbone where it's been broken tells me that's a bad idea. also you can say ass.

When I was competing in motorcycle observed trials I started learning how to fall off/with a trials bike. It took a long time- I am not graceful- but I was starting to get it at least some of the time. The argument above that road riders don't fall enough to learn how to do it is right.

Other than getting crap bikes and padding and riding around on a field crashing with other people, there's not much you can do for practice.
