OK, here's some pre-run intel:
As of 6-19-'13:
Here's the lower road sign.
The upper road sign.
This mattress is on the lower road, in a camp site.
Up at the top, by the first mine and the metal patrol shed, there are hundreds of shotgun shells.
And there are some other odd items that we'll probably want to haul out.
The upper road has two patches of ice, and the lower road has one. (Nothing we can't handle.)
No trees in the way.
