Ron - It is great to see you are keeping Cirkut photography alive. I'm always fascinated by these huge group shoots. Do you have one or more wranglers to get the people into position? Use any sort of risers to get the rear people up higher, or use one of the really tall tripods? I hope I'm not asking for your trade secrets. I can't imagine very many people with the energy to attempt a shoot like this, even if they knew how you did it.
