LI here, too. I have yet to come across anywhere but the beaches around here. If I hear of anything, I'll pm. Could you give me a heads up if you hear anything?
Your rig could totally handle a trip to Rauch. Don't try to keep up with your friend if he's going on major trails. I did the guided ride last summer and it was a blast. Green trails, but they had major rain for 2 days straight just before I got there. Mud everywhere. Totally worth the trip.
