Seminole Historical Society speaker: Before 1960, there was a narrow, two-lane bridge to Madeira Beach that was dangerous for busloads of children going to and from school. To allow safe passage, a brigade of women would stop cars at each end until the bus was safely across the old bridge. Women from the beach and women from the mainland volunteered to help daily. One of them was Martha Mohn, a charter member of Pinellas Seminole Women's Club. The Seminole Historical Society will hear Mohn reminisce about the club's activities in the community as they celebrate their 50th anniversary this year. 7 p.m. Seminole Recreation Center (Room 210B), 9100 113th St. N., Seminole.
