That I have an obligation to go to the CC tailgate. I have gone a couple of times, because you generally run into a person or two, but I usually don't go because they are lame. These are vacations for me, not charity events. I am going to do what is fun, and more times than not, there are a whole lot of things to do than to go to a CC tailgate.
Also, I am often there with my kids, and they generally hate them.
Next you are going to tell me I had an obligation to go to pre-game fireside.
