Sorry guys, I just realized that I had never responded to these messages. I know some guys wheel on the power lines off of Locklear which is the dirt road that runs next to the Masonic lodge on Blythewood Road by I77. I have never been on the trail behind he Comfort Suites, I will have to see if I can find out some information about that. As for the site mentioned, I am not on that site but will definitely check that out. Exit 33 on I 20 is out towards Leesville, that would not be a bad weekend trip at all. Of course I need to get some more appropriate tires and a bit of lift under mine before I adventure on any tough trails.
I will update if I come across any good trails or find out any potential areas to ride.
