Okay so I've found new apps that made this attempt far easier.
Just a quick update. Robin found us a new return flight after spending all day on the phone while I drove--yes AT&T has cell access in the deserts. The flight isn't until Tuesday, and will be leaving from San Francisco so we crossed the Sierra Nevada, climbing out of the moonscape deserts and up into Sequoia National Park and wandered around the giants. Then yesterday we pushed north and entered Yosemite, where we climbed waterfalls, went biking, and spent the night in a one of the tent-cabins they have here. This morning I am sitting in the lodge as it is surprisingly, one of the first places we've found with wifi in days and I'm writing this post as a squirrel runs about the couches and stone fireplace.
Hope everything is better on the east coast, and that if you are reading this that you have power and aren't just at a coffee shop.
