I attended a few Watchtower Conventions with my mother. She took notes. I was bored silly. Most of the time. I liked the dramas though they were amateurish.
Mom had started a book on Watchtower history from the Knorr era to present. Uncle B was not interested for various reasons. So she was working that on her own. So we attended various meetings, went to old-timers houses and chatted them up, looked at photo albums and such. She never finished it.
Finding meaningful documentation was a challenge, and it was my first introduction to serious research.
