I may have been there before, at least to the one near SML. It's at the end of route 666 (gasp!) in Bedford/Franklin Co. (I forget - it's near the co. line off rt 122 - a couple miles from hales ford bridge)
Not really much going on there as far as we could tell...there was kinda a driveway at the end with a gate and gargoyles or something dumb like that...
I grew up maybe 10 min from it...
