Sorry if I got your hopes up with the title,
Me and Aaron/Duderocks5539 met up at the Mt Baldy Fire Department on June 3rd to see the Denver test, but due to it not being wired they tested the Model D instead. It was my first time hearing one of those smaller Federal Signal model sirens and was nicely loud.
They also let us go on the roof of the fire department to get up close to the Denver, bearings were still great!
