The Coltsville Vintage Base Ball League competes from May through August wearing the uniforms, using the equipment and adhering to the rules and culture of the 19th century game before it became a professional sport. It was a “gentleman’s game” where camaraderie, sportsmanship and team play is emphasized over batting averages and individual accomplishment. 11 a.m. Free.
