I've been doing a lot of these sorts of projects lately but it's real good fun. This was the biggest so far, and I cataloged a total of 53 SD-10 series sirens in Texas, with the vast majority in the northwestern and Panhandle sections of the state. Borger and Abernathy had by far the most per town but a good deal of towns had two or three. Only 14% of the sirens I found were inactive, a pretty good percentage.
