I was just going to search Q drops for Lexington and Concord. Is this the only message with them or are there others, do you know?
I see three: 992, 2436, and 3907.
On qanon.pub there is a search box in upper leftt corner, type in "Lexington" and this is what you get.
Sometimes searches this way are not complete, if all cap for example it may not show.
