One can only think that this is what is going on inside my cranium when I am listening to music in my truck. My brain is being turned into formations inside my head. No wonder I seem to lose all ability to drive. I've seen the effects my stereo has on the smoke coming from my cigar and mouth. Kind of interesting.
The police in DC are experimenting with bass as a way of warning people to get out of the way. Seems everyone has become immune to the constant shrill of the siren when the cops are responding to a call. So they have outfitted a couple of test cars with subwoofers that play a constant drone of bass aimed at the ground. It is enough to make the area vibrate as the car is moving. They are testing to see if that gets people's attention better than a siren. Or if the two will work in unison better. The bass only plays for a brief period of time. Like for 5 seconds when approaching an intersection.
Beer, the reason I get up every afternoon.
