I'm a big advocate of eating and buying local; both for our own health and the health of the environment. Luckily, the city's many awesome farmers' markets provide that connection. I love to stroll the Saturday Union Square Greenmarket, check out what's in season and observe the interaction between the farmers and city folk. Hawthorne Valley Biodynamic Farm is one of my faves—not the least for their homemade granola! Besides produce shopping, it's also nice to leave with a small bunch of wildflowers. And if I need a kick on that particular Saturday, I'll stop at the little school bus for a shot of wheatgrass juice (fast and painless!).
