I stopped one late summer night in a grove of old growth sugar pine. The first branches on most of the trees were over 100 feet off the ground and a lot of them (the branches) were dead. So I found a spot that was out from under any trees and set up camp. About an hour later a little Douglas squirrel started cutting down cones out of one the trees. Now, for those unfamiliar with sugar pine, the cones can be well over a foot long. They made a loud whistling sound followed by a resounding thump. I was so glad I wasn't under that tree. The little bugger kept it up until well after dark. I'm not sure what he thought he was going to do with them after he got them on the ground since the cones out weighed him by at least 5 or 10 times.
