I'm going to get to do a month and a half road trip this spring, stopping at lots of national parks. I'd like to be able to do short backcountry overnights at places like Guadalupe Mountains National Park, Arches and the Grand Canyon, among others. I will have a netbook, car GPS and Kindle and other gizmos that I want to have on the trip, but don't want to take hiking. But the areas I'm going to could be fairly warm, if not downright hot, at the time of year I get to go. I am concerned about storing the gizmos in the trunk without baking (frying?) them. Does anybody have recommendations for storing electronics in the trunk of the car when the car will be in a hot, probably sunny, parking lot? Thanks.
