12/18/2009 - The December 20th game has been canceled due to snow. Jim and I decided that prognosis of the local roads do not look good--they are certainly quite nasty right now--and the uncertainty around what the weather will bring. At the time of this writing, weather.com is predicting more snow on Saturday. We are gifting 5 XP to every player because of the cancelation and we may consider doing a make-up game at another time.
