Same here in KY! I celebrated the first day of December with a nice little 5 miles. Started off wearing a hat and mittens and 2 shirts, one short sleeved and the other long. By the end of the first mile the hat was off. By the end of the second, the mittens were off. By the end of the third, the long sleeved shirt was off. And I was considering stripping down to just the bra by the time I got home. It felt a lot warmer than 50F!
