I pulled EVERYTHING out of our garage and sorted all but two large boxes before it was replaced. I removed more than 7 boxes of junk, plus a water cooler with an extra water jug, a large microwave, a pac-n-play type thing, a large humidifier, one large bag of toys, one large bag of dh's clothes, more than 8 VHS tapes, and 9 metal folding chairs.
I still want to get rid of more...but I think it'll be one layer at a time. I still feel like there is just TOO MUCH in our house that is not used regularly enough to justify keeping.
So, there's my update. It took from 9am till after 10:30pm to complete.
