Frank from wikipedia
Fort Sheridan is a neighborhood spread among Lake Forest, Highwood, and Highland Park[1] in Lake County, Illinois, United States. It was originally established as a United States Army Post named after Civil War Cavalry General Philip Sheridan, to honor his services to Chicago. When the fort was officially closed by the Army on 3 May 1993[2], the town remained as a civilian settlement. Most of the original housing structures were refurbished and the residential community has grown substantially in recent years.
