On a short hike up Slough Creek in Yellowstone National Park, we stopped for a brief break near the creek itself. A beautiful spot with clear water and a sweeping view of the surrounding mountains, we all started getting swarmed by horseflies.

As we swatted the horseflies and one landed in the water, we noticed some cutthroat trout patrolling the area. Without our fishing rods on this particular hike, we decided to see whether we could attract a cutthroat to the surface if we threw these dead horseflies into the creek. This video illustrates the millionth attempt.
