Well, here we go again.
Harold Camping's predictions of the Rapture on two occasions in 2011 didn't really pan out, but we now have that Mayan calendar thing to get through this year. Unless the Mayans pull it together and issue a new calendar before the end of the year....
I thought I would start the year with a word of caution for anyone who might think it is a good idea to ring in 2012 by participating in a Polar Bear Swim. Here is a polar bear swimming (thanks to David for the image!). I don't think you ever want to be this close to one, unless it is your final wish.
Enjoy your year safely!
