Signs around here are made of thin plastic sheet stuff, not the corrugated. I've been thinking of cutting up the wire stakes, though, to make new hoops for our croquet set. We have lost some and the wire on the signs I have are actually better quality than the old croquet hoops. I also wish they would come get them. Otherwise, I plan to take 'em to recycling. Had windows installed by Home Depot and they also left a sign in our lawn. That one I plan to return next time I go there, as I don't want it around.
