South Central, I am glad you had a good time.
There is a lot of variation even in JW Halls. I found JW Black and Hispanic congregations I was a member of in Brooklyn and California, much more welcoming and friendly. The comments and music were more lively, and some halls ignored headquarters' rules and had picnics and ball games.
There is a non Denominational church a block from us and a Unitarian church that send out neighborhood invitations for Classical music concerts, Madrigal concerts, and various events. We have never attended any events. I think Watchtower$$ poisoned that well for us.
