Cars make excellent solar cookers, don't they? There are a couple of approaches that will help. First, use and cycle items that are stored in the car a bit faster. This is fairly easy for food, less so for meds.<br><br>Where you keep things in a car will make a difference. Place things under a seat or anywhere else that is not normally in direct sunlight and wrap them in something that will insulate. Consider a styrofoam cooler if you have the space. You may wind up storing perishable items in different locations from nonperishables that otherwise would be placed together. This shouldn't be too much of a problem as long as you and your family know where everything is.
