Both of these books are available for a very reasonable price from Amazon.
Edna and I thoroughly enjoyed our visit with these two professors. Dwight said Edna looks worldly but I am worldly. Another observation from Dwight who he is good friends with Ollie Troyer from Kansas. He saw some Troyer similarities between Ollie and the two of us. That was an amazing observation being we are 7th cousin with Ollie.
