Actually, the USA instructions say that baptized and us baptized pubs along with their minor children will be allowed at this event, so expect screaming babies and restless children just like at any other meeting.
and the letter that will be read at tonight's service meeting explicitly says the AGM will last 3 1/2 hours, so 'plan accordingly'. It also tells everyone they should carpool if possible, and to be seated before the scheduled start time.
