March 1st--Spring??

I've been experimenting lately with wearing fewer layers, but today, for the first time, I went to the city without any long-underwear, wool socks, down jacket, scarf, hat, gloves, or snow boots! It was a gamble, but I think it paid-off, as I am completely comfortable, and not sweaty in the sun under all those unnecessary layers. Could this really be spring? I'm not making any bets yet that my down jacket can go in a box until next winter, but for now, it sure does feel nice!
