I've been going to the Richlands for more than 10 years. I rolled a pathfinder, stuck a Cherokee in the snow and had to walk to 321, and survived a roof flattening end over end in a Toyota. The sketchiest thing I've ever seen is a stuck 2wd C10 with a hooker running into the woods. @UNBREAKABLE
I just checked the link and I didn't see Richland on there... I haven't driven the trail since fall 2016, is it still legal to off-road there? Assuming you stay on the main path and don't stray into the private property?
