Not recently, but during my tenure as president, we had to evacuate for a fire alarm. Since it was a Saturday, there wasn't anyone around to ask when it was safe to return. I searched the VA center campus and found a security guard who wasn't aware we were there. So he came later to tell us when to return. On another occasion, there was snow during the meeting, but it got bad during the after lunch class. The teacher was very cooperative, shortened the class, and sent us home with a pattern to finish. He was available by email for questions and we posted our pics to his FB account for him to see.
