Thanks to all for the humor and insight shown so far.
I'll be curious to see if any crackdown actually occurs. I have a gut feeling that it won't happen unless these events start getting a little too "wild". But so far they've been very wholesome, (fairly boring) and actually a healthy social outlet. As a general rule I've not seen any alcohol present which probably helps keep things from getting too rowdy for JW tastes. If a serious crackdown was implemented it would hit the JWs locally at a gut level. It would be very bad for "morale" and I think everybody knows that. So, even though it goes against Borg direction on "Christian gatherings", I think they'll continue.
It seems to me that for about 10 years or so, the only big gatherings were weddings or going away parties. Then about 5 years ago (around here, US West Coast) more parties just for the sake of having a party started happening. Has anyone else noticed a similar trend?
