My aunts small cong merged with another small one in her KH (that had 6 congs and now has 5). There are rumors that two others will merge soon. That will make meetings on Sundays easier, Iguess!
My moms KH has 3 congrgations. I don't know the size.She is in an affluent area and it is about 10 miles from nearest hall. I will say that I have not seen a lot of new KH's. Or any. Today we drove by a KH that has always been on a route from visiting my aunt. It is in a small town in the mountains. It used to be kept up, landscaped and looked cheerfull. Now it is still a KH, but other than the storefront ones with bars that I saw in the projects in the Bronx, it was about the saddest looking hall I ever saw. Weeds abounded in the parking lot, the paint looked dull on the building and the sign. You could practically see tumbleweeds blowing through. This is an area with a lot of hispanic families and I doubt any close KH's. Not affluent. It was a beautiful day and everything else looked enchantingly beautiful (mountains of W. Washington on a sunny day in may-stunning!) but that place looked like it was cursed by an evil witch. It looked gloomy and had no businss doing so on such a beautiful day.
