Did an exploratory run up around Amicalola Falls State Park on Sunday (similar to what Jbzhow did around New Years).
Took GA-400 up to Dahlonaga and the GA-52 West (we have tried GA-53 West through Dawsonville to GA-136 and found it to be a pain).
We were looking for a better way to Springer Mtn than going GA-52 way past Amicalola Falls State Park to Roy Rd. to FS42.
We took the Nimblewill Gap route -- Nimblewill Rd. to FS28-1 to FS77 then left on FS42 coming from the other direction. This was lots of fun and without any mud on it could probably be done by any vehicle with AWD or a 2WD light truck with enough clearence. If you are trying this on a rainy day, you would defintely need the 4WD.
We came back out FS42 (though next time we are up we want to explore FS665, which is season closed right now and see where it goes) and turned onto Roy Rd. trying to find the 'Newbicon Trail' (Old Bucktown Rd.) entrance to the closed Anderson Creek OHV area. We did not find this but we did find the closed FS357 entrance.
We continued down Old Bucktown Rd. looking for FS28-2 to cut through, but could not find it (too many private drives and new construction), so we will have to come back up next time and try it from the other end where we know it comes out .
All in all, a good time. Forgot to bring a camera or GPS (both would have helped). Next time.
