My husband and I have a theory that squirrels will run for the nearest tree - even if that takes them directly across your path..... check it out next time you are riding or driving and a squirrel runs 1/2 way out, then turns around and darts in front of you yet again. He's probably running for the closest tree.

Not to scare anyone, but I have seen pictures of forks broken clean off from squirrel strike. Usually it doesn't end prettily for the person or the squirrel, but it is rare.
