I was chasing all over Montana when the old 600mm was being used. My job took me near Yellowstone, and the Tetons. Oxbow Bend used to be a quiet place to photograph Elk, Moose, Eagles, Osprey, and OTTERS! On this occasion I waded out to my waste in the very slow moving river. Across was the family. They are an absolute riot to watch and photograph. Always touching and interacting. What a close knit family.
