Whelen WPS-4004, Voice & Alert, Harwood Heights, IL (4/6/21)

Went to this LOUD 4004 today with my brother. The original plan was to do a Glenview thunderbolt with Alex (Wi Sirens & Elevators) but traffic decided not to let me. We then set our sights on Schiller park, but then I noticed we could make it here. This ended up being the second loudest siren I’ve ever heard. This thing threw some INSANE echoes as well. We were also questioned twice so thats cool.
