Three days a week - Mondays, Wednesdays and Fridays - Arthur Ward, his wife Brenda and a handful of dedicated volunteers set up a small white canopy near the north end of Butterfly Park, located at 3717 W. Meinecke Ave. in the Metcalfe Park neighborhood. As Milwaukee Neighborhood News Service reports, the canopy is a signal to park visitors, mostly children, that dinner will soon be served.
