My buddy & I decided to go "off-road" with our street bikes somewhere out around Fredericksburg on a dirt road that went thru a town(?) called Hye. I was in the lead on my Guzzi clipping along around 20mph when we came upon a pasture of cows to the right. In the middle of this group was one very large mad bull who apparently had an extreme dislike for italian machinery. He began charging me and running along the fence line. I was laughing so hard that I wasn't paying attention to the road ahead of me. All of the sudden I realized that the fence ended open with no gate or cattle guard in place and the bull had ran into the road after me. About this time my buddy on his H-D fat boy came cresting over the hill behind me about 20 yds. He had just changed out the carb and pipes so when he gave the hog a wrist twist it made the most awful loud popping and backfiring noises that you could imagine. The bull upon hearing all of this commotion (probably thought someone was shooting at him) stopped in his tracks and did a reverse back into the pasture. So it is true that Harleys with loud pipes do save lives.
