rode here for the first time on sat, great time. Trails are in good shape. One giant tree down in the middle of the trail that you need to cyclecross over but, other than that, i enjoyed myself.
Might be worth a shot since it's supposed to be hot and sunny tomorrow.
This might be the one place where you don't need a guide but I can suggest you start from the boat launch/main lot. Starting from the cushetunk lot is absolutely brutal. Plus the view from the main lot is just a great way to start and finish your ride. Well worth the couple bucks they charge to get into the lot this time of year.
