Were you ever on a congregation picnic? I was on several occasions.
The arrangements were often announced from the platform after the closing song and prayer by the last elder up on the platform.
Sometimes it was included in the Service Meeting Announcements as "on Saturday we're meeting at 10.00am at the Kingdom Hall for Field Service, and after Field Service for anyone who wishes, especially for the younger ones, we will be having a congregation picnic meeting at the beach carpark on Seaview Road."
Well, according to the new Elders Manual you won't be hearing those words again. Lol.
