With all the mergers of congregations in our area, I can't imagine how anyone could keep up with attendance figures.
We attended the Memorial and I did not know 70% of the others attending. Twenty years ago, I knew nearly everyone in the Circuit. The elders with whom I am well acquainted that had been the shakers-n-movers were not involved unless it was a prayer. The speaker was a 30-something who is new to the area as he married a local JW gal. There appeared to be plenty of 30-something guys who had stepped up into leadership positions. (Not sure that 2/3 of young JWs are abandoning the religion here. * ) At least 50% of the men were sporting beards.
( * Hate the new beard policy. Used to be you could see a JW you new on Facebook and if they had a beard then you knew they were inactive or POMO.)
