You probably spooked his date. You didn't see any sheep or loose cows wandering nearby did you??? ;) Quoting Joe Bauman <bau@desnews.com>:
Fiddling with computer and camera and telescope, I heard something scuffing rapidly along the road. A deer, I thought. I had seen several deer beside that route before and I did't want one to stumble into my cords, table, chair, etc. So I let out this loud "WOO!" to warn it away.
"---you!" yelled the obviously startled deer. It was a young man hiking along the road. I said I was an astronomer trying to use my telescope, and asked what he was doing. "Walking along the ---ing road, what does it look like?" he shouted. As he trotted off, he said, "Hillbilly!"
Hillbilly? Hillbilly? That didn't compute, until I realized the locals must call each other that when they're being insulting. He must live in the area or he woudln't have been on such an obscure stretch of road in the middle of the night.
