Yeah - what he said! Just downloaded the file to BaseCamp.
I 'discovered' the bridge above Spanish Fort in '07 and love the run from Lake Nocona to Ringling, especially just before dark, on a hotrod bike. There are some dirt roads up in that area, around the Lake, but I've only ever run a couple of them and that was in the truck, before I was "corrupted" into the DS mode.
Yea the bridge was great discovery for me too, albiet 7 years later than you I just happened upon it looking for ways back over the Red River. I rode through Spanish Fort this weekend and it looks to me like they are getting ready to tear town the General Store. The building next to it has been demolished.
