How to be cool….let us count the ways.

* Listening to and appreciating jazz;

* Keeping a cool head while parenting, especially while being green;

* Cruising in a cool car;

* Getting up to the microphone to perform;

* Easing on down the river.

Below is your personal Petaluma guide to coolness. Good luck.
