My son lives on a wooded parcel in a geodesic home, so he has a deck that encircles about 3/4 of the home about 20 feet above grade. My wife and I often visit him in the afternoon to cook out, then hand feed whatever birds will trust us, and right after the cardinals leave, the flying squirrels come gliding in to put on the feedbag. Before he bought his home, and given the many thousands of hours I've spent in the woods, I'd seen only 1 flying squirrel, an accident. I cut down a rotten (hazardous) tree which broke in two when it hit the ground. There was a blur of movement as a squirrel exited his hole, climbed about 2 jumps up one tree, then glided to the base of another tree before climbing up out of sight. Never having seen one, it took some thinking to figure out what it was.
Good memories.
