Waking up to Gunfire and Coyotes

My fan was running, so it was difficult to hear exactly what was going on, but I woke up to loud bangs and howling coyotes. I don't live in the kind of neighborhood where gunfire is common, but that's what I heard. Howling coyotes are common where I live.

I was questioning my sanity when a few minutes later, I heard it again. This time, I turned off the fan and went back to bed and waited. Soon I heard a truck roaring up the hill. It screeched to a stop. There was loud squealing from the machinery and then several loud bangs as it dumped its load. It was just a dump truck. What a relief to realize that I was neither insane nor suddenly living in a bad neighborhood, it was just my over-active imagination.
