On the south edge of Jackson, Wyoming, just before the developed area peters out, lives this sign. There it is for all southbound traffic on US 89 to see. It's not a tiny sign - probably 4'x8' - and I first saw it a month ago.
The flip side has a smiley face and no words. The sign is near a restaurant and bar named The Bird, and could well reflect that proprietor's unique sense of humor. Perhaps he paid for it.
