DUNEDAIN:
I would tend to agree with what you say: fewer halls will ultimately mean FEWER Witnesses. This will be the unintended consequence. Unless, of course, this is what they want:..fewer and more hardcore JWs....Who cares?
In the long run, more travel time to distant halls, resentment and tired people will cause this to happen. What about inclement weather in the wintertime? They're crazy if they think people are going to drive at night.
Some may have mentioned that because the Witnesses got used to using tablets, this will mean they will just accept the idea of longer travel times to new distant halls. I'm not so sure. Maybe, initially, a few won't mind and will be real positive but time will wear some out not to mention those already disgusted by all the changes and the religion's neverending appeals for money!
At least I won't be one of the fools driving to these distant halls!
