bdiddy,
Your Thanksgiving plans sound like a Chevy Chase movie. I hope it goes well.
About 10 years ago my mother thought it would be a good idea to rent a house on a lake and have my sisters, myself and our families together for an extended weekend. I thought it was a really bad idea but I kept my mouth shut and went along because it was my mother's dream.
A couple of weeks later my mother told me that if she ever suggested something like that again, that I should just have her committed. I hope your family get's along better in closes quarters than mine did.
