About 12 miles of trails, only open to the public for this event. To ride them any other time, you are racing one of the 2 races held here. Sweet trails, with marked and bypassable sections of more aggressive trail.
Large MX track, hosts the Loretta Lynn's qualifier each year. MX track is run by classes, so you dont have to worry about not being the fastest, you will be matched to your machine and ability.
$35 gets your days ride, coffee and doughnut breakfast if you are early, free lunch, and the knowledge that you are helping a a fine 501(C)3 charity that gets the funds to the kids, not to administration.
Any and every rider within trailering distance should be there, you WONT be disappointed.
Look me up, big guy, pony tail and beard, cant miss me...
