Ask yourself this, out of the 6K members of DU, and the quarterly fleecing of said DUmmies, has anyone ever seen a DU bumper sticker? They're given out for donations. I always get one because it cost them money.
Yes, I actually have. I saw it last summer, in my area. The car looked about how you would have expected it to look. I haven't seen it again, so I may not be in the right place, or the right time, or they may have just been passing through.
