Happy Pi Day. Or is it Happy Pie Day?

Either way, we think celebrating pi (3.14 etc.) on 3/14 is a good enough reason to grab a piece of pie and ponder the mathematical universe. But really, is there ever a reason not to celebrate pie?

In honor of Pi and Pie, we offer up a dozen of our favorite Sonoma County pie shops, and a few of our favorite slices therein.

Petaluma, 707-766-6743,

Mom’s Apple Pies – Sebastopol: The scent of apples and cinnamon hangs heavy in the parking lot around this classic roadside bakeshop.

Kozlowski Farms – Forestville: A vivid reminder of what West County used to be.
