Actually, you need at least two checklists, now that I think about it: one for your trip, and one for the home front while you're away. If you need to board a pet, make sure your spouse/partner doesn't forget a medical appointment, make arrangements with a neighbor or the Postal Service to pick up your mail, or set up something for your child while you're gone, better put all that on a list too, lest you find yourself scrambling madly via cellphone to get things sorted out that could have been handled easily while you were still home.
Now to follow my own advice ... see y'all on November 2 in Lexington, I hope!
