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.
