The Siren Board

Found this neat article about emergency preparedness near the Comanche Peak nuclear power plant which is southwest of Ft. Worth, Texas. They have a system of Federal Thunderbeams.

Most, if not all, of the Thunderbeams have been replaced with 2001s. It must be an older document.

It must be, thanks for the update. Good to know.
