I am from around there and I think you can drive off road at Rausch Creek. It is in Pine Grove, Pa near Tremont. I have never done any off roading there but I have been to their motocross track so I couldn't tell you if it is good for beginners. Here is there main website http://www.rauschcreekracing.com/rcmp/modules.php?op=modload&name=Contact&file=index
Go to the 4x4 off road section on the left under Motosport Parks.
