I don't think that anyone is disputing cranking on a V8 at 2:00 am is the wrong thing to do. I have a car with a V8 that screams. The nights that I get home late, I keep it as low as possible becasue it's just the right thing to do. During the day is a different story.
Some people have no consideration for others and that's too bad.
I hate rap music with a passion. I have to listen to it at every stop light, every street I walk down and just about every store I walk into that has a young kid behind the register. I don't let it infuriate me and ruin my day. I don't walk around showing these people noise ordinances telling them that what they are doing is inconsiderate and rude. They know and they don't care. So I just drop it and laugh it off.
Those of you who don't like loud engines are in the right. However unless you have law enforcement that will enforce the laws or boaters and bikers with consideration, your up a creek without a paddle and that's unfortunate. And no I have not been to the Lake, Yet.
