This morning, I heard the city of Cedar Park - just north of Austin - passed a noise ordinance about the loud car radios. A person can be fined up to $500 on the first offense if their car speakers emit noise so loud it can be heard or vibrations felt at 30 ft. That will be about 90% of the rap listeners.

I hope Cedar Park does a good job of enforcing the ordinance. We have ordinances here, but they are not enforced.
There was a kid waiting for the traffic light about four cars away from me the other day, and his speakers were louder than the freight train a block from 183. I could hear his “music” over the train’s air horn blasts. You can bet he won’t be able to hear a thing in 10 years.
