Started out in Bozeman, stayed a first night in Mammoth Hot Springs, stayed several days around Old Faithful, and then back to the Mammoth Hot Springs area for the Wolf Discovery tour.
Wolf Discovery Tour Van Lamar Valley, Yellowstone National Park, Wyoming
This van was really nice. The windows were either double paned or were heated because they never fogged or iced up. There was a shelf above the seats for storing my camera gear. - February 07, 2011 - 1/500 sec at f / 11 - 48 mm - ISO 200 - 44°53'44" N 110°14'4" W
