Rafting

We’ve had this white water rafting business for a while now.
We load up the trailer, head upriver, and then Bart and the rafters head downriver. Then, I drive back down with the trailer.
We used to work out of the cabin upstream, but folks preferred to do the road trip first.
They also like midnight runs, but they’re not safe.
Tonight, something went wrong. I got to the downstream cabin and saw the boats floating down the river.
I check with a flashlight. Nobody in them, splattered with blood.
It’s a full moon.
Howling.
As I said, not safe.
