I'm driving to school this year, and I want to keep some CD's in my car. I'm just worrying about them getting hot and warping. I want to keep them in one of the zipper cases with the different "pages" or slots in it, and store them under the seat. I put a sun reflector up in the windshield and crack the windows when its not raining. Will they get to hot, and should I put keep the pouch in my locker during the day to keep them cooler?
