Colin's Disorganization Disaster

How did my basement/garage become such a disaster? I'm a single parent with four amazing kids. Well, is "kids" the right word? They actually range in ages from 11 - 21. Obviously, I have limited time for cleaning and organizing. The basement/garage has become the dumping ground and storage area for everything and everybody. "Everybody" includes not only my kids, but FOUR generations of family! I am storing belongings of my grandparents, my parents, myself and my two brothers, and my kids. Yup, FOUR GENERATIONS! Ultimately, I would like to organize these belongings so I can park my grandfather's 1953 GMC truck in this room and start restoring it (currently, this truck is sitting in our backyard). Boy, do I need help!
