I've got a stop sign, a deer crossing sign. I also have a route sign that I stole from one of the 1500 backroads here in the boonies.
Me and some friends attempted to steal a "Welcome to Kentucky" state sign that is on a non-main road. Didn't look like anyone was around while we were working on the sign and then a porchlight comes on. This old redneck comes out with his dog and goes "You kin take it if ya wannit!" At which point we ran like hell back to the car and the old man just laughed at us as we scrambled in and sped off.
I have two CD's from Walmart that I intended to buy, but the old lady cashiers can't seem to tell two from one. Ah well, not like Walmart needs that 20 bucks. They should've made those ladies greeters.
At the local airport here, they were doing some roadwork and had some cones set up. They are I guess about three feet tall or so, maybe shorter, and heavier than I would have thought. We took three of them and stuck em in this big exit ramp curve in the town. Just some (more or less) harmless fun, no way to miss all of the cones, as soon as you turn the corner you were gonna hit the plastic cones or take a chance in the other lane. We had one car come by and hit one and swerve into the opposing lane. After setting it back up we drove up the ramp (in the opposite lane) ourselves to leave and a truck came down the ramp. He must've got pissed and just took them after he plowed em, because 5 minutes later when we circled around they were gone.
