I was on several of the lettered trails: A, T, Q, R that I remember for sure. Whoops so bad you would need a bull dozer to flatten them. I honestly like the trails at Dirty Foot Mud Ranch much better. I'll still go up to croom during the week when Dirty Foot is closed but I'll stick to the very back where the technical trails through the mining pits are, and maybe on my way out stop at the front pit just to get some air under the tires.
go to the lettered trails north of the back pavilion. (north of the mines)
