happened upon this place, by accident, after exploring the Copicut Wildlife Management Area. even tho it's a long drive for me I'll be going back. lots of trails over 5,000 acres. many roads open year round, many seasonal roads, motorized dirt bikes allowed seasonally. lots of dirt parking lots, but also several paved official parking areas. anyway, lots to explore!

from what I could tell the ground isn't like Myles Standish, which is sandy w/ pine needles. this area is more hard packed dirt with rocks
google street view by a dirt biker. this trail or road was gate closed when it was taken

some pics of mine from the Copicut area South of the Freetown forest

lots of intersecting roads & trails

park roads are not paved such as Payne & Hathaway. when I was there 2 days ago the gates were open

this is Payne Road

TB2 (whatever that stands for) was gate closed. by the looks of it, probably always closed
