We had agreed ahead of time to go to the Cheesecake Factory at the mall for lunch. As I had feared, there was a bit of a wait (30 minutes is what we were told; 40 is closer to what we experienced), but we had phone/tablet/book to entertain us, and we even got a bench to sit on or a good chunk of the time. They dropped beverages and bread and butter and oil pretty quick after seating us, so we didn't even mind the wait for our food.
T. and R. went ice skating. The lunch outing did not take so long as to prevent T. from doing that.
I got a message from the town police department that the big booming noises were from Fort Devens. Excitement! And apparently more in coming days, but ending at 4:30 each afternoon.
R. took A. to a drive through McDonald's for lunch.
