The photographer arrived in Yellowstone in the late afternoon of day one of his visit and left in the early morning of day three. It was windy, cold, and wet the entire time he was in Yellowstone and the photographer loved every minute of it. Unfortunently we lost 2 rolls of exposed film. Not good. Everything was shot with a Nikon F with a 28mm lens. Vistas, vistas.	Visiting the park in May and June might make you wet and cold but the crowds will be much smaller. Even with the smaller crowds it's best to get out earling in the morning before the families get roaming. We had almost empty roads until 10am in the morning. Remember we were up at 4am, stopped for breakfast at 7am and saw what we wanted to see by noon.
