Thanks to all (as always, this forum is great). We'll take the Hobeck/South Park route out of Jackson. After climbing the West side of the Sierras, the various mountains in NV and up into West Yellowstone over the Targhee grade (plus the 600 miles of driving in the parks), both myself and the F250 could use a break before having to climb over NV and back into California ;) We've heard a lot of great things about Massacre Rocks and are looking forward to finishing out 15 days out there before the inevitable return to reality.
Happy travels!
