Ours had vandalism where they would run over the lawn and if a new sidewalk were put in brothers would have to watch it until it dried so that neighborhood people wouldn't write things in the cement.
On the subject of a hall being held up: while I don't know of one personally I do not go to the hall with much jewelry on just in case somebody came in. Although, isn't that what the big "bouncer" brothers in the back of the hall are for, to protect us? In this day and age, I feel that people in any public meeting group can be targeted by some brazen person that decides to come in. So that goes for other types of meetings held in church basements, etc. like Al Anon or other such things.
I don't trust anybody today.
