and you can keep up with trip reports and photo ops in Yellowstone as they are happening. I just came back from 20 days in Yellowstone. I preplanned my shoots by monitoring this site since last October. I was able to tune in those areas most likely to have animals. Shot Bighorn Sheep, Elk, Bison, Coyotes, Black Bear, Grizzly, Trumpeter Swan, Geese, Mergansers, Eagles, Hawks, Osprey. Enjoy.
