I have multiple old digicams laying around and I was wondering if it would be safe if I left one in my car? I figured I could use one if I ever needed to snap a pic on the road, or if I was in an accident. Would it be a bad idea to leave a camera in my glovebox for an extended period of time? Would heat and cold temps be a problem? What about the battery? Would I have to recharge it every few weeks?
