I would guestimate + or - 2000 acres. Iam no surveyor so dont take my word for it. I know there are a hand full of loops that take a good part of 20 min to complete. I here there is a 7mile loop but have never been on it. A lot of these trails are only accessable by 4x4. You will see a mix of all types: sport quads, 4x4 quads, mx bikes, and trucks. Sometimes there are some outrageous sized trucks in the mudhole.
yea i know they get some big trucks out there, i was talkin to chuck from chucks trucks and he said he goes out there somtimes, and he builds monsters!!!!
