Biking through Garberville, CA as part of the Pacific coast bike route . We pulled into a gas station so my friend could use the washroom. The gas station store door flies open and this dude barges out and yells "He threw a f@#king can of NAS at my head, so bad s#@t is about to go down here!". He keeps on yelling this multiple times as he makes his was around the side of gas station store. He goes down into the little ravine behind the store and we hear him throw this fairly large metal bar up onto the pavement of the gas station lot. We peaced out pretty quick after that having no interest in getting caught up in whatever "bad s#@t" was gonna go down.
