I lived through the 1975 shit show as a child. My mom still denies to this day that the watchtower promoted the date.
I know some need greaters moved to our congregation from Edmonton before 75. One family got disgruntled and left in 76. I still remember the father coming to our house and telling my parents how it was a sham. I wish they would have listened to the man.
The whole 1975 move to some backwoods town had a huge impact on peoples lives
