I just got word on this: http://freewheelbike.com/about/daily-news-feed-upcoming-events-ride-info-pg634.htm
They have top of the line stuff you can reserve and try on the trails out at Murphy each week. I would suggest calling and reserving the Fuel Ex or Top Fuel... but I am partial to 26" wheels=)
And ouch! Apparently they got a few chuckles over me and my Salem-mud-modified bike. Thanks for documenting things Tyson and thanks for the weight reduction tips Chris.
