On our Train Trip, we went to the Organic Farmer’s Market, held each Saturday at this Encinitas (CA.) elementary school.

Encinitas has an interesting Mosaic history. My favorite story is a community battle over a piece of art deemed “graffiti” (because it was illegally installed). Here’s an article about it.
