I think I would have done this checking and rechecking, but we ended up just diving in a few years earlier than planned, so I know I'll just have to wait and see if it'll work.
If I had FIRE'd on schedule, with all my ducks in a row, I'd still be checking to see if they're in the row, or wandered off. Since I know I'm already short 2 ducklings from what I was planning, I'm just not worrying about it. We probably have enough, so let's see. :)
