We have a new style kh here, built near freeways, hotels and a large medical clinic. Its small. The gates are locked all the time, shut when meetings are going on. Its weird. Local mormon churches have gates open during activities, jws are in there loke its jail. In my area are 2 halls, 2 English cong, 2 spanish and 2 others. Vietnamese and Cambodian, I think. Never seen a jw on the streets or my neighborhood except when one of them thrust a tract at me in mcdonalds parking lot as she was headed to hall one sun morn.i guess her half hour walk was a good way to get in some time.
New hall is a single, adequate parking. Both old and new halls have high security gates. New hall has many windows, old hall has none. An old hall on other side of freeway in a nice neighborhood with beautiful grounds is gone now. I think they are in storefront locale.
