Well, regardless of when winter starts where, sleeping outside in a tent in October wearing nothing but shorts and needing no sleeping bag isn't normal for Michigan.
The next "what's going on" weather check will be using the winter commuter to run between the polls on election day. It's never warm enough to use the summer bike and no top layer, and frankly I enjoy going in and having to take off the thick gloves and top layer while the precinct workers shake their heads and pull their sweaters tighter around their shoulders.
So, I'll hold off on any more weather judgments until after 06 November 2007.
