Fifty five years and counting

My 55th high school reunion was a great success.  Eighteen of the 51 graduates showed up.  Some have passed away while others where not well enough to attend or just didn't want to.  And then there were those we've yet to locate.  At any rate it was a great visit for those who did come.  We shared many happy memories.

Here's the crew.  See if you can pick me out. The man seated in the front is the only teacher to attend.  He taught math and was very popular.
