It's been a year since Tom Scheidel wrote this invaluable thing, and pretty much all of it is valid. There are a couple of updates, though, numero uno being cell phone coverage. Due to a stubby little tower right near the playgroud, there is now one billion times more cell phone coverage. AT&T folks even get 3G data; Verizoners have to make due with just coverage. Once you're away from the oasis, though, that coverage drops away reeeeal fast.
