This message is from Bill Friedrich:
Before Engine 104’s station was closed, these were the last fire companies that operated 24/7 from that location. Michigan Avenue wasn’t very busy on weekends back then. After the station closed, Engine 104 was reassigned to Engine 1’s station, and 4-2-4 was moved to Engine 26’s location. It was a sad day for this historic firehouse, which had served the community for many years.Bill Friedrich
