The Berks County mom heads north to Alaska with her brood, at eight hours, their longest trip ever. On their trip the family hope to see snow-covered mountains, glaciers and whales. Along the way the kids get to try a ride on an Iditarod dog sled, to Kate's chagrin; the family gets to pan for gold in the river and take a boat ride out to sea to hopefully see giant whales leaping in front of them.
