After driving through 100 degree temps today (the temp inside our not-air-conditioned vehicle reached 108) Jason decided we should have more comfort when trying to sleep tonight. So he went to Kmart and bought an AC unit for the Vanagon. (Don't worry, we're not using this for driving! This is while we are parked at an RV park.) A few bungee cables and some other stuff, and it's up and running.
