I did so much searching, navigating, and camera swiveling that one of my fingers literally bled under the nail but it was worth it, clocking in 31 P-10s and P-15s. It was almost completely even split, with 15 P-10s and 16 P-15s. Only 26% of the sirens were inactive. Every single siren was located in the northeast or northwest quarters of the state. Even more interesting was that a good portion are mounted on metal poles. Wylie and Greenville (Both in the DFW metro) had the most.
