John has been riding off-road for over 25 years, 20 on the mountain bike and 8 years as a singlespeeder.  He discovered 29inch wheels 4 years ago and has not clipped into a 26inch bike since.  He's also been known to pass a rider or two every now and then.   The Eastern Missouri IMBA rep has been advocating/building trails since 1999 and thinks that there's no excuse for bad trails.
