Brennan Field was home for two seasons (1996-97) to the Will County Cheetahs of the Heartland League. It is located on the campus of Lewis University. In the early days of independent baseball, a field such as this was sufficient. But this is no longer the case. Brennan Field simply consists of some wooden bleachers set up around the field. The wooden pressbox doubles as a concession stand. Good enough for a college team, but nothing more.
