No Helen, i am not on vacation - had shoulder surgery last Monday and was off-line for awhile. My recollection of the sit-in was that it was for the cancelled pep rally mentioned by Karen- and it was more or less a big ground swell - don't really know if there was a single organizer.
As for the Latin teacher - y'all might have had the nickname of Sister Ubi - but her real name was Sister Xavier Gibbons - came from a religious family in Pittston (couple of brothers were priests, and i think had a sister who was also a nun) - think she passed away a few years ago in her late 80's (i might be mistaken about her death - but think my mother did say semthing about it
