You guys are really working hard! Booksaver, that sounds like a huge project.
I got one of my 2-drawer file cabinets cleaned out. It will be full again in a year. We have 3 2-drawer file cabinets and 1 5-shelf bookcase stuffed full. Another 5-shelf wire unit and a whole closet of shelves. All I can do is try to keep things as cleaned out as possible and tidy, in boxes and bins or plastic containers all labeled. It's a good thing I even have this space to use.
Goodwill people told me not long ago that they no longer have a truck which will come to pick up furniture. I know they came here a few years back to take the old entertainment wall unit away. He said it was really nice, or I wouldn't have called them to come.
Every few weeks I roll out my recycle bin and by then it is full of plastic and paper. I must be on every mailing list known to man, and we get so many catalogs. Sometimes I bring the mail in through the garage and put the catalogs right into the bin. Trade magazines go out the minute I'm done reading them. If I didn't keep this up we'd drown in paper.
