Welcome to the site :cool:
Be sure and go to your User CP and update information relating to your location, type of riding, etc. After that grab a spot on the couch and tell us a bit about yourself. How long you have been riding, what kind of riding you prefer, where you are located, etc. We will do our best to hook you up with some fellow dirt bike enthusiasts.
Check out the
Kentuckiana Chapter forum for opportunities to get out and meet some fellow DRNers. Say hi to Jaybird, he can steer you to some great riding spots.
Good luck with the knee, keep us up to date and check out the
Riding/Training Techniques - Injuries forum for injury/rehab info.
Again, welcome to the site and shout if you have any questions!
