Bloomington, Minnesota had a very interesting system back in the day. They had Thunderbolts, a Screamer or 2, Allertors, and 2 SD-10s. Majority of the sirens are replaced except one. A Thunderbolt 1003 located on an orange building in eastern Bloomington which was installed in October 1978. It was deactivated in 2019 but still up as of current day.
