At the campsites at this particular Corp Park, they use what Dan and I would call heavy duty metal clothesline poles for hanging your lanterns on. We use it for our bird feeder and apparently the others that stay here do too.
The workers who stay on this site in the summer time must've had issues with squirrels getting in the bird feed. There is slimy evidence on the vertical part of the pole having had Vaseline smeared the entire length of it. At one end of the horizontal part of the pole have been placed 2 plastic "rollers" that were made by cutting out both ends of pop bottles. They must have worked because even though we have squirrels, we have not had an issue with them trying to shimmy up the pole.
The squirrels we have noticed seem very friendly, but they still are squirrels.
Here is a couple of photos of one of the friendly little guys (and we KNOW IT IS A GUY).
Dan was tired of looking at those old plastic cut out bottles and was going to take them down, since we weren't having any issues with this little guy. Oh, but I've forgotten to post the other photos....
He's kind of like saying 'ARE YOU LOOKING AT ME? I'M INNOCENT! I'VE PROVEN THAT TO YOU!!!
