I've listed some things on Freecycle in the past, and just plain set stuff out by the curb. In either case it all went to homes where it was usefull again, I'm assuming.

I've been on both sides of the curb, so to speak.

I can't resist checking out people's stuff setting at the curb. I've gotten a perfect condition metal tub for my fire pit ashes, and a nearly perfect condition mini igloo cooler for my fishing worms from someone's curb. Saved me from having to buy them at the store.

I've put stuff out to the curb that didn't last 20 minutes that were surprising that dissapeared; stretched out waterbed mattress, kinked garden hose, half working stereo, broken pole lamp, and a couple mostly bald tires.

Hey I truely believe in 'one person's trash is another person's treasure'
