I went again to the restaurant this morning, to get breakfast but also to take advantage of the free internet. See, I realized there was a bit of a problem with my planning: I was looking at going through Parker to Twenty Nine Palms, but that meant 110 miles and 1500 feet of elevation gain with no services and the possibility of nowhere to stay along the way. It might be that's no big deal, but I'm not really interested in risking it.
