Never seen a sign, but that's not too surprising since it's all rural roads and there really aren't any signs to speak of. I've picked up a few license plates. Generally I drop them at the cop shop as I go by. One was a magnetic dealer plate from the Ford dealer I use; I took an extra 5 mile loop to drop it off to them that evening, and they were VERY happy to get it back; apparently they're pretty expensive, and the salesperson who checks it out is responsible for it, and I saved him something like $150. I thought about waiting until he was in to bring it back and seeing if I could get s/o/m/e/ /f/u/e/l/ a pizza from him.

If I did see a sign, I'd probably either leave it there or take it to the cop shop. I don't really need more crap around my house.
