I know leavin a board in the car for an extendedperiod of time is a bad idea but what about when its a bit colder. Like tomorrows gonna be about 55 where i am and i was thinkin about leavin it in the car while in school. itd be in a boardbag too. This sjouldnt be a problem, should it?
whether it's your board, your dog, or your favorite sabbath album, it has to do with other factors besides temp. if the sun is out, the greenhouse effect will raise the temperature dramatically. i'd find shade and crack a sunroof or window for ventilation. also depends on your neighborhood. in some places someone will bust yer window to steal a bag from a car; they'd ventilate your car for you in a heartbeat.
You should be OK. In the summer it gets to over 100 and as long as your board's not cooking in the sun, it's no problem. Your car won't hit 90 tomorrow, especially if it's parked in the shade or the windows are cracked. Then it will stay in the 60s.
