I'm not quite sure if this is the right place to post this one, but here goes.... My question concerns having equipment while you are out in location and NOT with you. I live in Central Florida and summer is coming. That means day time temperature will reach 95F and possibly higher. In vehicles parked outside, it can reach 130F and higher even in shade. I try to minimize equipment I carry and keep them with me in shoulder bag but this isn't always possible. I have a large cooler in my trunk (a type that often used for beer, etc, at tail gates, picnic, etc) and keep my equipment there for short duration. There is no ice in it so condensation is not a problem. I have not done this in middle of the day or for very long time. What do you do, if you must carry lots of equipment to field and you can't carry all of them with you? By equipment, I mean cameras, lens, accessories, films, etc.
