When I was a kid the family would go to Yosemite Park for a couple of weeks every year. There was an outdoor ampitheater (sp?) in the campground where we stayed.
Early in the evening before the show started we used to watch the flying squirrels jumping between the trees that were around the setting. I could never figure out how they flew until I was told that they just glided.
They were fun to watch anyway.
