The one question that kept coming up was some variation of, "Can any non-Mason visit the Grand Lodge, and, if so, how does one make that happen?"
On Thursday I went down to the Grand Lodge for the Scottish Rite's Maundy Thursday Ritual and I asked.
Here's the answer. Yes, you can visit. You probably should call first, to make sure that someone can take you around: (615) 259-3434. But they would love for you to stop by.
And if you are a giant history nerd, you will love visiting.
