I dont think if there is any single track it would be leagal but there is a good ammount of double track quite a few side roads I did not explore.. Friends who jeep tell me there is quite a bit of un maintained road I have to go back and check it out a bit more myself.. Lots of good gravel in that area not technical but scenic stuff Islip rd is quite scenic but no challenge.. I doubt your looking for nice gravel and more like I typically am in search of good single track though..
