This is actually in the Bamber section of Lacey Twp. It is not Double Trouble. It is on the south side of Lacey Rd.
I have not been back there in 15+ years. I remember it being very sandy with practically no hard pack.. it's mostly fire roads and an old railway in the area surrounding "FR Mtn". We used to ride moto back there.
I think this is mostly if not all private property and I have heard the police can be sticklers about trespassers.
