Several years ago I was in Yellowstone watching and photographing the Sloughs and was fortunate enough to have them all to myself. A small car pulled up and a man got out and began watching them with me and started telling me who each of them were by their name. He asked if a minded if he could stand with me and take some video which I of course didn’t mind. When he produced this monstrous movie camera a new he just wasn’t just another tourist. He introduced himself as Bob Landis and I was lucky enough to spend at least an hour with him. Great guy and I can’t wait to see this film.
