to add to the rabbit hole, there's this:

One masonic website lists CASTLE ROCK, South Dakota, as the 'geographical center of the United States'. Previously, I like many anons associated Q's use of 'Castle Rock' with Castle Rock Studios, which presumably has been involved with filming MSM video clips that make Biden look 'presidential'.

I guess the inspiration for the film company's name may have come from this masonic geography reference - but also might Q have been referring to Castle Rock, SD? The Castle Rock (Belle Fourche) area of South Dakota is about 80 miles north of Mt. Rushmore, which is an area Pres. Trump has talked about a lot.

Here's a bit more that I found - identifying St. Paul, Minnesota as the 'geographical center of North America':

some interesting maps/emblems on that page.

Makes me think of how Minneapolis - St. Paul has been a flashpoint for all the BLM terrorism these past few years, and how masonry might be involved in that.

There is this document from the masons about their "International Peace Garden" which straddles the Manitoba-NorthDakota border area:

The International Peace Garden is 2,339 acres situated on the border between Manitoba and North Dakota, on the longest north-south road in the world and almost at the geographic centre of North America. It was dedicated on July 14, 1932 and has become a living monument symbolizing the two nations living in harmony along the longest unfortified boundary in the world.

Now, the International Peace Garden is about 200km west-southwest of Winnipeg, so I'm not sure precisely where the masons consider the "geographical center of North America" to lie. But it seems they regard it to be in that general vicinity.
