rock run is definately worth the trip. i was out there the week after fishers atv reunion and we pretty much had the place to our self. Spent two full days there and it was really good riding. I really like how the trails flow together nicely. I rode for about an hr straight crusing at like 20-25 mph through the trails and it was awsome to go through the different terrains of the park without loosing a good rythm. While we were there we got caught in a severe thunderstorm and i was flying down the main access road at like 50mph on my raptor and it took almost 20 min to get to the parking lot from the back of the park. the place is definately big and well worth the drive. plus they have a warrior on the front of there brocure!
they had a couple hill climbs some nasty mud/water pits. and some really rough rocky trails. overall though it was just awsome the views made it even better
