Speaking of temperature it is awfully cold out. You might be thinking it’s far better to just use a warm locker inside, but nay I say. That cold car just doubled as a giant refrigerator to hold your lunch! On the hot days I would probably advise against storing food in your car. Unless it’s coffee with no cream. In that case you should park where you can get fresh sun and leave that coffee in the window. If it’s no hot by the time you get back to it then at least it’s still kinda warm!
