Has all the info you'd need on campsites (the new deluxe version). The one around Ross is pretty nice, but its easy enough to pick as you go.
I don't know what your assigned campsite is, but as an FYI, if its Slickhorn C, I would request another from BLM. There is a serious oil slick/spill type thing happening down there. Whole camp reeks of diesel and the mud is inundated with it.
