I had an extended time in Southern Utah during March. This was around the Escalante area and beyond. I camped and backpacked with my hammock and HG hex tarp, and it worked out great! I used to be less confidant at finding hanging locations in the desert, but I had no trouble on this trip. I never had to "go to ground", but I seldom had two living trees to hang from. I did have to start looking for a campsite a little earlier in the evening to make sure I found something suitable.
As a side note, I tend to hang my foot end of the tarp lower, because I use a narrow foot bridge. This is working well for me. The tarp was needed more for blocking wind than for rain on this trip.
Here are some highlights of my hangs. Enjoy!
