I am going to sound like salesman here:
Rock Run is located in Patton, PA( very far away from AR). It has over 140 miles of trails with primitive camping. They are suppose to get electric hookups and a bath house next year, but i think they said the permit process is taking longer than expected. As for picks, I'll post them soon(wife's phone).
As for riding, it can be very rocky. The map and trails are clearly marked. One thing I like is there is a main artery, so having 2 kids I can get back to the truck ~5 minutes from just about anywhere on the grounds.
Summer blast is their main event of the year. It used to be Fisher's World Reunion, but no longer. Below is the link:
Rock Run Recreation Area - Trails for ATV, OHV, SIDE BY SIDE
I enjoy the place and have a camp ~5 miles away. Even though the riding is great and hardly ever crowded, Polaris(this is nothing new) is prominent at this recreation facility. Just wanted to see if any Honda's were coming out anytime next month.
