I love farmer's markets. Eating locally produced food is important to me. If you're with me on this, then check out your local market! I have several that are near me. The Oakland County Farmer's Market on Pontiac Lake Road is now open Tuesday, Thursday and Saturday and they have some great vendors. Hartland and Howell have markets as does Royal Oak. Later in the summer Clarkston will start up. And, of course, the Eastern Market in Detroit is legendary. My personal favorite is the Walled Lake Farmer's Market.
The Walled Lake Market is on Maple Road next to the Fire Station. You can find fresh-baked breads and cookies, pickles, tea and-my family's personal indulgence-the BEST tortilla chips in the world (try the "Secret Recipe"). Currently, you can also buy your own plants for your garden. Later in the season you will be able to find yummy produce at great prices. The market runs from 7am-1pm on Wednesdays. I'll be there tomorrow!
If you need to find the market nearest your house, go check out Local Harvest.
