On Wednesday, October 11, 2017 at 7:00 p.m., the Grayslake Historical Society will host a program about Warren Township High School. Before Grayslake Community High School opened in 1946, Grayslake students attended neighboring high schools. One of these schools was Warren Township High School located in Gurnee, Illinois. This year Warren celebrated its one hundredth birthday and alumnus Jim Lodesky will share stories that he learned while researching the book he has written about the school. The book will be available for purchase after the program and refreshments will be served.
