I live outside of Prinsburg, MN, a town of around 500 people. The city limits are about a 1/4 miles square and they have one S10 located in the south central part of town. They got a thunderbolt from Willmar, MN five years ago with the intent of putting it up by the fire hall on the west end of town (this has yet to happen and I'm after the T-Bolt). The sirens would be located about 3-4 blocks away from each other.
My question is: Is it even necessary to have two siren in a town this size?
