This picture might jog some memories. It was taken at Big Pier about 1961 (give or take a year).
I can't remember all the girls names, but in the top row starting at the third from the left is Carol Eggers, Peggy Weeks, and Wendy Shull, with Barbara Brown at the top right. Bottom row left is Cherie Ellis with Nancy Boudet (fifth from left), and Faye Brown.
There was never a shortage of girls at Lake Shore Park.
