Ha! An easy one for me, I live a block away! Tho I passed a cemetery this summer in Hooker Township about 30 miles away. There was a big arch over the entrance that sayz "Hooker Cemetery" (fill in your own joke here!)
OK, next mark. Something that might give non-US riders a bit of a leg up, but easy for everyone.
A letter/postal carrier on their route. Could be a carrier in uniform with a shoulder bag or cart delivering downtown or a suburban carrier in their postal vehicle at a bank of mail boxes, or a rural carrier in their own vehicle as long as it says "Postal Service" or the like on the vehicle. The hard part will be getting the shot staged if the carrier is on the move.
Why a letter carrier? Considering the financial state of the US Postal Service and the fact that they will need Congress to bail them out, a letter carrier may be hard to spot in the future!
