The Memorial Day parade ends either at the cemetery on Concord Rd, between Rt. 27 and 2A, or the one just outside of west Acton, on Central St. I don't remember there ever being a Veteran's Day Parade. But, I think Concord has one and maybe that's what your son marched in, Deb?
I only remember Josh coming home from the Columbus Day and St. Patrick's parades in Boston, telling me about "the gross drunk guys who run out and try to pinch the girls' azzes," while they were marching .
