Very few agencies publish their freqs. I have never heard of any other agency that offers ridealongs to the public. Who are you guys?
I'm someone who may have been monitoring fire frequencies for too many years or may have visited too many fire agency websites.
I don't want to rain on anybody's parade but a fair number of agencies publish their frequencies on the web.
And even if they don't, just about anybody can find an agency's frequencies by a web search, often in a matter of minutes.
Ride-alongs are not so common but they do exist. Many stipulations apply, of course. A dress code I can't forget goes: "grey or navy blue shirt, navy blue pants, black shoes-- black tennis shoes OK."
Antonia FD is to be commended for its public relations.
