Now here's the story. Our brief - but strong - shower had just stopped when the squirrel showed up. I had missed her earlier trips up the pole to the bird feeder, but caught this one. Only she didn't make it - slid back down the wet pole. She tried it 3 times. Slid back down 3 times. Finally she backed off, got a good run at it, jumped up 2/3 of the way and managed to get to the feeder. For her efforts, I let her stay a little longer.
