Dogbone1, I'm not an MTB'er at all, but I will reccomend to go to
www.bikeclicks.com . It is a louisville based site that covers alot of KY's cycling activity. I know they have a "click" or two for mtb riders. Some people say the site is sort of tough to navigate, but hang in there. It has alot of good info and active riders within it. Also, the yahoo group purplerides has active racers posting group rides and etc. Right now, the focus is turning to road (as road season is nearly here), but it's a good place to creep around on, if nothing else.
Hope these two place will be a good start, Wilson - from south central KY
