Downtown to ring with the sound of cannons and muskets on Monday

Alert the Harvard Business School alumni association: The Ancient and Honorable Artillery Company holds its annual leadership change tomorrow, and that means a march around downtown with frequent firing of muskets, with even more musket fire - and cannon fire - on the Common between 1 and 2 p.m.

In April, a Business School alumnus sued the Ancients and Honorables and the National Guard for $20 million for what he says was permanent ear damage caused when he wandered onto the Common on the first Monday in June, 2015 at the height of some howitzer fire.
