Some friends and I were looking into heading out west on a road-trip just after Christmas. As of right now, the itinerary is something like Nashville-->LA (in other words, the straight-shot that is I-40), so through AR, OK, TX, NM, AZ, CA, and maybe UT and NV (slight detour). Since we will pretty much be bumming it, camping seems the most cost-effective and logical approach to our overnight stays. I was just wondering if anybody has any experience camping in late December/early January. I'm sure it won't exactly be toasty even during the day, but I'm willing to layer up as long as its reasonable.
I also noticed a lot of campgrounds shut down after October or so, but from what I've found, there should still be plenty open that time of year.
