I've been in my current home, a condo in a well developed and growing part of town, for seven years. I've been retired and mostly at home for the last five. I have NEVER been contacted here by JW's. I'm thiry miles and 25 years away from my disassociation so I'm sure they have no idea that there's an apostate here. I lived in a rural area outside the city outside the city for about 8 years starting in the mid 90's. We were contacted at least three times there. Clearly preaching is not being pursued the way it was.
I don't know if the org will die, there will always be some sheep needing direction. But something serious will have to change if it is going to regain the fire they had when I joined during the run up to 1975.
