Type: Federal Signal Thunderbolt 1000T
Signal: Alert
Location: 904 Logan Street, Louisville, Jefferson County, KY

For my last test with the Tri-State crew before I head off to college, we hastily chose this 6M Thunderbolt near downtown Louisville. We did not expect it to be this low pitched, as it appears to peak below chopper level 1. Regardless, it was still decently loud. Enjoy!
