After having reached the furthest point of my ride today I hit "Go Home" and thought I'd try some different roads and let the 350 autocalculate to get me back. While at the top of a small mountain it would have had me make a right turn directly off it. No road, secondary road, path, or possibility. Just the dirt nap. Never experienced anything like that before. It occurred to me later that I should have stopped and entered that as a bug-spot. Will do if ever in that area again.
