Evening Anons so just took tiny hop into the rabbit hole. And I got a tingle thought and want to ask if librarians, of all people, might be worth a longer look? They have all sorta of "programs" and conferences and meetings and travel. I jUmped when I saw a private charter from Astoria to Arapahoe Co and that was kinda weird so did a search on any connection and came up with library director who has had some interesting old addresses. Worth a dig or lurk moar?.
