I'm living in Las Vegas, Nv, where the temperature tops 100 degrees nearly every day in the summer, and I'm afraid to leave my ipad in my car for long periods of time, because the heat could damage it. I was wondering if anyone knows of anything I could store it in my car in, for an 8 hour period without it overheating. I don't think a cooler would work since the ice would melt too fast in the kind of heat experienced here in Vegas.
