I can relate! I remember riding one day (long, long ago in a college far away...) on a woody path and a squirrel trying to cross the path ran parrell to me for several feet before giving up and going back from whence it came (or at least behind the bushes). I think it was trying to go thru my wheels, but since I was moving forward...

It did kinda freak me out for a second, thinking I was going to either flip over or run over that furry thing!
