So I don't know if this has been posted and what the other connections to this might be (rookie patriot), but thought I'd might as well share it.
On January 5th there was a 'Yellow Brick Road' found in Crystal, MN. On december 22 2017, Q posted (post 435):
‘Yellow Brick Road'.
F-I speech - history.
Wizards & Warlocks.
Alice & Wonderland.
Solved?
Q
There is loads of crystal symbolism around the Wizard of Oz - so the yellow brick road in CRYSTAL, seems pretty significant. And a cute quote from the Wizard himself: ''Then suddenly the wind changed and the balloon floated down into the heart of this noble city, where I was instantly acclaimed as Oz, the First Wizard Deluxe".
