These galleries result from a three day trip to Tetons national park followed by almost three days in Yellowstone park, as part of a photographers' Meet and Greet photo trip inspired by Bill Bates and the Canon DSLR forums on www.Dpreview.com . Each of the galleries contains several photographs, culled from a much larger number of shots taken during the trip. Most photos were taken with the Canon 20D camera and the Canon 17-55, Canon 70-300 DO IS lens, and the Canon 100-400L IS lens. Several photos were taken with the Canon G7 digicam, and a few were taken with the Canon SD500 digicam.
