Me too. I did a two-week elders course back in about 1970 in Pittsburgh or so and it was on an optional bus tour for one weekend. Weird stuff.
Schroeder and Davis were the instructors, they made a little speech before we went to just ignore some of the symbolical graphics. They also took us by a couple of the old buildings where he used to preach - one was I think a community center and another a church auxliary by then.
The course was held in a kind of big super-kingdom-hall which somebody told me has now been sold and probably torn down for building sites.
BTW, I believe there is a Freemason's lodge somewhere close around there, but as far as I know it was not a "solely Masonic" graveyard - if there is such a thing. Both my father and grandfather on his side were 32nd degree, my other grandfather the honorary 33rd degree, and all were buried like most Masons in a church or public graveyard of the family choice.
