I think the only real way this gets done is to do a little every weekend. How do you eat an elephant? Ideally, I would love to pull every last thing out of the garage and then sort it and put only the good stuff back. BUT it's not just my stuff in there and there are no shelves or storage of any kind, so the stuff that went back would just be a disaster. If I can get everyone to agree that no new stuff goes in, then it's easier to sort through what's in there a little at a time. Easier said than done, but here's hoping!
2013/03/08 I've been cleaning garage every day since Sunday (03/02/2013). Moved metal shelf from shed to garage. Moved tools & wood out of way for shelf. Moved stuff to shelf so I could put ladders in corner. Repurposed small white wire shelf that was where the ladders now are for folded clothes in my closet (killed 2 birds with one stone). I'd say another 2 days, and I'll be done. Goal: fit car in garage (and have room left over).
