We signed up to go on the day-long bus tour of Denali National Park - 13 hours long. We had lucked out on the weather. It was a gorgeous, clear day. We were told that it is rare to see Mt.McKinley; the weather is usually too overcast. We also saw lots of wildlife: grizzly bears, caribou, moose, dall sheep, Arctic squirrels, and a wolf. Our bus driver told us we had the "Grand Slam" tour.
