Something came through town this evening with a sound and rumbling so unique it portraid evil and fear. It was heard and felt from the top of the rim, the power could be felt, as it echoed and shook the canyon and on around the bends. It was a monster powered motorcycle scary, insane acceleration, as you could hear the twist of the throttle, as evil crept through the canyon.

Later that evening and after a little digging, this is what I came up with, but it still does not describe what I heard and felt..from a good distance.
