Ken, I'm having trouble with the relevance of the CBS 1pm games. What matters for the start of the Amazing Race is the 405 or 415pm games on CBS. Here they are:
MIA @ BUF 4:05 PM
NE @ SEA 4:05 PM
KC @ DEN 4:05 PM
NYJ @ SF 4:05 PM
The maps for distribution of these games do not appear to be available yet, but I will make a guess that they will cover most of the country and the probability of a football delay is very high. For you, Peach and Chateau at TARCON XIII this might not be good news. For me, with a special service to sing at Sunday night, the latest possible start is fabulous.
