Mother's Day redux

Skip ahead to the mid-seventies . . . here's a picture of my mother where everybody else in the picture is a science fiction writer or fan.  I think this was New Year's Eve at their place in  Tarrytown, I'd guess ca. 1976.  From left to right, that's Gay, yours truly, my brother Jay (Jack C. Haldeman II), Mike Glicksohn, my mother, and Risty Hevelin.  I believe the drinks that look like iced tea are almost pure boubon . . .
