That's true, especially at night when AM propagates farther. And when tuning a high power, clear channel AM station.

When I lived in Irvine, California, the city had its own low power FM broadcast capability. I heard it put to use one time, when a wildfire was headed towards the edge of the city. That's the only city I have heard of with its own broadcast capability (as opposed to going through commercial stations through the EAS). I'm not sure if the transmitter was at city hall or perhaps up on the nearby hills, but I thought that was a great resource for residents.
