i know zman's crisis was resolved but if you leave a board in the car, even with a bag, the wax is going to melt and it could start delaminating. thats when the glass and foam separate, usually leaving a soft spot on the board and you do NOT want that to happen especially to a new board. i know in some people's cases they have to bring their board to work or leave one in the car, but it's good to take as many precautions as possible if you want your board to last a long time.
