Boy are these guys lucky. A couple of tourists reported missing after a visit to Yellowstone National Park were found safe on the Beartooth Highway, where their car had been stuck for nearly a week. The owner of a guest ranch heard about the missing couple and went looking for them on his snowmobile. He found them at about 8:30 a.m. Monday and took them back to the guest ranch. Mark and Kristine Wathke of Cornell, Wis., were cold and hungry, but otherwise OK.
