Today I drove around Blue Hill Nebraska as I had a hunch they had another siren in addition to their 3t22. I didnt see anything but it was getting dark and I didnt check the whole town.
I went to lunch in Cambell Nebraska and while I know they have a T-121 by the water tower, I had a hunch their old whistle was still up and I was right, I found a Sterling M-3, and it's ACTIVE! It did a 1 pm blast so it's being used for time signalling.
