Personally I love to go bike riding during the winter. The cold has a nice contrast to yourself. 8) As a added bonus you don't have to feel guilty about the holiday eating (Thanksgiving, XMas, New Years Eve) after the bike ride.

Of course I can do without the snow. With snow on the road I can't ride using my racing road bike. 8( The reason is because I am very likly to get killed by black ice or snow that is on the road.
