My grandson is a full blown siren nerd, er, enthusiast. It’s so cool. Like locomotive train dudes, and other stuff like gun guys. Sorta. He’ll be 15 soon but last couple years taking him shooting he’s like a hawk and can see an old fire station siren. He’ll know the name and manufacture/model number, generation three, etc. We’ve had to run off the road so he can shoot pics of a siren. I could go on, but I just wanted to know if anyone has ever heard of this hobby? I mean, he has files and a web map of the ones he’s recorded. Yesterday we were getting ready to go and the local fire department had their ladders up and then the siren went off, funeral, and he got to record the sound and the horn going around. I know it’s better than dope. Love him!
