I was wrong.
We had just enough people with exactly the right skills to get this done. Any more people and we would have been tripping all over each other.
We had two guys with professional furniture-moving experience,(a ghodsend), and a couple of other strong backs who actually listened to directions. We had the organizational skills of a couple of moms and a control freak. We had an indefatigable 5 year old who was happy to run up and down the stairs fetching things.
Thanks, Guys. You were AWESOME!
