In July of this year we did the Chilkoot charter tour with dog kart. My daughter we was 8 loved the dog kart ride but is wasn't very long. We were also signed up for the helicopter dog sled ride in Juneau. We got all the way dressed and in the helicopter. When we got close to the glacier the weather turned bad so we had to turn back. The company was really nice and they said it happened often. They gave us a full refund and we got a helicopter ride..
