Well this thread certainly has brought up long forgotten memories! Yes, I remember the 15 minute breaks! Yes, we kids used to run around in the parking lot (lots of admonitions about watching out for cars and maybe NOT running around in the parking lot). I also remember some going out for a smoke. At some point (maybe after 1975) when it was the rank & file JW leaving during the break it seems THAT was when they stopped the break because too many witnesses were leaving after the talk...not just studies.
Anybody here used to go to Sqaw Peak Congo in Phoenix? (Sorry for the politically incorrect name but that was what it was called). This thread brought back all kinds of memories of that place to me.
