SOUND MYSTERY

Maybe thirty minutes ago, as I was sitting here in my room, I heard a siren go off outside that I've never heard before in the four or so years I've been living in the Presidio, louder and deeper than any automobile-based siren could be. After it wound down, a deep, amplified voice spoke some words that I couldn't make out. I don't know if it was related. I could not identify the source of the voice.

I've heard noises like the following before:

- A police siren
- A cop talking into a megaphone saying "Pull over!"

This was not that. I wonder what was going on. I swear I am not making any of this up.
