For those of you interested, there is a web cam at the last camp where the guys stayed -- you can see regular photos of the camp but also a picture of Adam and Dave. If you scroll through the photos and look for the one stamped 11:09, you will see them. Kinda fun. I imagine that after today the photo will have been replaced with others.
