I practically live out of my car being a commuter student. So I keep some extra clothes, books, paper, pencils, water bottles, hats, work out clothes, and flip flops in the back of my pathfinder! But I NEVER, and I cannot stress NEVER enough here, leave any food in my car under any circumstances. And I febreze the hell out of my car at least once a week. Kind of an "organized, clean crap heap" kind of deal
