We got to know Bill and Ann at the University of Illinois, where Bill was a Post-Doc under the same professor with whom I was working, Peter E. Yankwich. They moved to Arizona when they left Illinois, and we visited them there several times. When we drove from the east to the west coast, in order to catch a plane to fly to Taiwan, we would stop off in Arizona. In 1982, they came to visit us and we went to several local places, including Grand Father Mountain (three pictures below), Watauga Lake (one picture below), and, of course, the Smoky Mountains. We really enjoyed their visit as we had enjoyed their company when we were at Urbana in Illinois.
