I was talking with one of my brothers recently, and he commented on something he's noticed while travelling. He noticed that a lot of kingdom halls seem to be popping up in rural areas. I know that a town in the next county built one outside of town a couple of years ago, and the KH in my own town has a 'for sale' sign on the lawn. (Not sure if they built a new one outside of town or not, though. I haven't gone looking.)
Is there a trend towards moving halls outside of city limits?
If so, why?
