DEER HUNTING SEASON in Pennsylvania is still a month away, but someone has announced an open season on the "Caution Deer" signs along Northeast Extention of the Pennsylvania Turnpike. Aside from the usual bullet holes that such roadside signs inevitably attract, some prankster or pranksters unknown have adorned the leaping buck on the diamond shaped signs with a bright red applique nose. This particular sign is located on the side of northbound lanes of the turnpike about a mile south of the Hickory Run service plaza, although it appears that every deer sign between the Lehigh Tunnel and Scranton has been given the Rudolph treatment.
