Small towns---I live in one---often have a community-wide Yard Sale Weekend. I'm always amazed at the number of out-of-towners who show up for ours. The streets are lined with cars.
We also have a "clean-up day", in which you can put anything (except paints/toxic chemicals) at the curb for pick-up. No charge. Ours was this weekend, so huge piles of mattresses, old furniture, appliances, etc., began piling up during the week. It looked like a third-world country!
Anyway, people will drive around and pull things they can use from peoples' junk piles. Most of my stuff (an unused cross-country ski exerciser, metal shelving, a de-thatching attachment for a Snapper lawn mower, an old built-in desk from my kitchen, among other things) was gone by the time the actual junk-haulers arrived yesterday afternoon.
Funny how so much stuff gets recycled. One person's toss-aways are another's "Hey, I could use that."
