Shirtless in December

We're having a spell of unseasonably warm temperatures in my part of the country, and lots of guys are eagerly taking advantage of the opportunity to go shirt-free.  I'm enjoying watching runners and bicyclists going by sans shirts on the path behind my apartment building, and from my vantage point on the 15th floor I can also see shirtless fellas playing on the tennis courts.  A nice little oasis of bare chest weather in the middle of winter.  Let's hope there's more to come!
