Moab/Arches/Four Corners area for sure. Also would like to get back to Lehman Cave and, though I've not been there before, maybe Carlsbad Caverns someday. Deserts and caves seem to be my thing, perhaps because I'm allergic to the majority of plant life and it is thus in those places that I can breathe most freely. For all that trees are beautiful, they still keep trying to kill me every spring. I grew up on a lot of roadtrips, and while I did enjoy Yellowstone and Yosemite a great deal, it is the Southwest that speaks to me most deeply. I've recently taken to collecting roadrunners as a sort of good luck charm/maybe power-animal-ish kind of thing, though I do recall being mightily disappointed as a child by their lack of resemblance to the cartoon. But then, the cartoon was mostly passive, though elusive, coyote prey, whereas the real thing is an impressive hunter famed for slaying of venomous snakes much larger than itself and even shows up in one Native American legend as a Prometheus-like fire-bringer.
