Thanks for all the input, everyone. I guess since I'm only going to be away for 3 days, I can't take the chance of a late night, early morning scenario.
It's weird, though. I live 8 train stops from the busiest airport in the world, and I can't find a decent direct freaking flight to Buffalo. They keep wanting me to stop over in places like Newark. Bah. I know Buffalo isn't exactly the metropolitan capital of the world, but it's not exactly Hayseedville. If I were going a little bit longer, I'd just drive.
Sorry, I'm all bitter about this.
