So then we went in front of the tree to try it again. But apparently there's a rule against lifting of any kind, because a second officer stopped us.
We still didn't get the shot.
The dancers were getting cold and stiff (it was 25 degrees!), so I decided to have them go back to the original bench.
We practiced the lift once on 5th Avenue,
and then they jumped on the forbidden bench and nailed it! I got the shot, we all got yelled at and nobody ended up in handcuffs. Perfect!
