A group of at least 100 motorcycles just passed in front of my home. I'd say that these people are the ones that keep JC Whitney in business. 99% of them were enjoying their loud, temporarily chromed, pipes, blipping their throttles and "racking off" after almost losing their wives or girl friends during an impromptu acceleration. What a circus of Hell's Angels want to bees. At best they were enjoying the noise. At worst they were making a social statement, saying, "Look at me, know I'm here and try to stop me from dominating your environment". These are the same people who would not put up with some idiot playing rap at full volume in a filing station. The result of their roostering is that the general public will have one more bad impression of motorcyclist. Impressions accumulate. I'm pro motorcycle and I wouldn't care if they all ran into each other and suffered whatever fate. You may say loud pipes notify others of your presence and enhance your safety. You may reconsider that thinking. See yourself as that guy in the gas station making everyone miserable. Yea, the one with the target on his back. Most people can restrain their anger, but one might not.
PS: One noisy bike at a time is bad. He or she is usually moving fast and is gone before tempers can flare to the point of action. Given the time for 100 bikes to go by, you never can tell what someone might think up as a response to their Sunday afternoon nap being disturbed. That would be the nap that they worked 6 days to enjoy and you just "messed" it up. Ride on brothers.
