Janice, hubby is a minor league hoarder too. It's a battle to get stuff thrown out. Even tho stuff has sat for a decade or more, he's sure that as soon as it's gone, he will need it. He's good at shuffling piles, tho!
Hope all goes well with the packing and moving. Just did it for my daughter and I ended up packing up most of the house while they worked. Pace yourself. You only have one back and it has to last you a while!
