There is a demand for locally printed whistles for communities where ICE is or forecast to be.
If you are interested in printing whistles for your area, search “ICE whistles [your area]”. You can use either your state or major nearby city. If you are interested in printing whistles, but can’t find anything, let me know and I can see if I can find a local org you can support.
I am very much of the opinion that ICE whistles should sound like those Aztec Death Whistles.
Oh man, can you imagine like 50 of them at once? That would be nightmare fuel.
