this is my first post in English so sorry for any spelling errors. so this thanksgiving break i went to see family in central and north California and along the way i visited some sirens and i decided to make a roadmap of sirens across the I-5. For anyone who is curious i saw the Fresno =SD-10 System, The Lafayette square 2001, Chinatown 2001, and the park metro east modulator which is one of two only installed in the state.
Here is the link to my map: https://www.google.com/maps/d/u/0/viewe ... 761653&z=6
Also on a side note: the entire map is written in my native language so you will need to translate it yourself sorry for the inconvenience.
UPDATE: I did a little bit more researching and google earthing and discovered there are few other modulators in CA but not many maybe like 4-5
