I live in a desirable area 25 miles outside of a major west coast U.S. city where there are lots of nice new houses, new large shoping facilities, new schools and new parks that have been built in the last few years. On the main road into town, there are 6 churchs within 3 miles of my house (not counting the K, Hall) l, all of them were already very nice but each expanded and have built on new and very elaborate facilities to their existing building. Their parking lots are full on Sunday and often people need to parked on the main road and walk to the church. Most of them are casually but neatly dressed rather than wearing suits and ties.
Our Old old Kingdom Hall is the same as it has been since the late 80's 90's when it was remodled. It still looks nice but In the last 8 years JW's have only called on us 3 times. It has been about 5 or 6 years since the last time anyone one calld on us. There used to be two english speaking congregations that met at or kingdom hall but I've heard that there is now only one english speaking congregation and our hall is made up mostly older people. When we attended, any growth came from when a JW family moved into the territory and there we no new converts. The other congregtation that meets there now is now a spanish speaking mexican group. The parking lot on Sunday for our old Hall is not very full but the spanish speaking Hall seems to have a normal number number of vehicles in the parking lot.
I think there is something going on because this summer when we drove by the stadium where the District Assembly was, there was only one parking lot being used rather than all of them being full the way they used ot be.
