I should sneak a Shaw church in this run of random churches. Vermont Avenue Baptist is at 1630 Vermont Avenue NW.
In 1957 Vt Av was a HUGE church claiming 3,600 members. They had 3 Sunday services with over two thousand congregants showing up on any given Sunday. It was a predominately white collar Black church with 41% living in the urban renewal area. About half the membership lived in the rest of DC. So about 1000 people coming in on Sunday, where did they park?
