Next few years will be very interesting if they do go full on fire sale with the halls they want to close. Fewer halls is going to mean longer commutes.
This is 100% their plan, as stated by a RDC /LDC rep from NY Bethel a few months back, to a joint BOE meeting of multiple congregations.
Their stated goal is to have 3 congregations per Kingdom Hall, worldwide. It's not a secret, they are telling everyone they meet with about their plans.
That's all well and good in New York, LA, Miami, etc., where there are many KHs with 4 or even 5 congregations.
What about Podunk West Virgina or Fumbuck South Dakota, where it's 1 congregation per KH and the next KH is 50 miles away? "Keep warm and well fed, brothers, and don't forget to gas up, the service station may not be open by the time the meeting is over."
