Most appear to be social clubs.
A few here and there are the church that the Lord intended.
The church I visited....for the last time this last Sunday...not my church families Church btw.....is fairly good sized...with the inverted ships hull architecture with many fine stain glass winodws , a Pipe Organ.....and VERY FEW worshippers.
I see, I was raised in that old time religion, my parents would recognize America churches today.
