We returned books, she got a couple things in the parking lot then I read my kindle in the car while she walked around to the war memorials to get a few more, where she had an Encounter with a couple fire fighters (there's a fire station on Concord Rd. there), who apparently are part of a large search for a woman. They very apologetically asked her for her id and they chatted for a while.
This was a _lot_ of excitement for returning library books and playing Ingress. We came home. We figured if we could have this much happen returning some books and playing Ingress, we really shouldn't go anywhere near, say, a bar.
ETA: My efforts to find out further details (searching the web, google news, twitter) haven't found anything useful. Let me know if you are more successful than I have been. Don't get distracted by the 2012 incident involving the Southington, CT woman.
