I received a note from Bruce Edwards, Jr. suggesting the identities of the men in this picture. I'm certain that's James Kee on the left. He began teaching at Dulles after Bruce graduated, so I don't think he'd recognize him.
In your Pool picture, I think the 2nd from left is A.C. Boozer, superintendent for Southwestern Construction at Imperial for many years. 3rd from left may be Jimmy Couvillion (manager of Western Auto).
I saw Wayne Boehm (SLHS '55) at the Chautauqua Talk last week, and he identified Lloyd Tyer. In fact, Wayne knew all these men pretty well. They were neighbors, relatives, or guys he bought cars from.
