Practice to learn the system for several peeps. The ducks in my view were very high, and I was not happy with the second one so came back. Was waiting around and cold, so worked on the stretcher in being a cas. Once we released I did a small trip in the near reaches, before going back through with Ian, this time in the right frame of mind and took Ian to rough chamber. Dan hartley had me film sections before Rich convinced him to come through the ducks.
