Living in Silicon Valley it is easy to overlook the fact that California is the nation's agricultural powerhouse, leading all other states in farm income. Over 400 crops are gown here, from almonds and avocados to peaches and pistachios, and you can find many of them at your local farmers' market. Now is a great time to visit a market, with so much fresh produce in season. Most towns have at least one weekly, often year round market - check out the listings at the California Farmers' Markets Association (http://cafarmersmkts.com/farmers-market-locations), if you want to be sure you are buying direct from a farm. There are also many other legitimate markets, you can simply search on line for a selection near you.
Another option is 'pick your own'. Many farms and orchards cater to the 'u pick' crowd, some with activities to entertain the kids when the novelty of gathering their own fruit and veggies begins to wear thin. The site www.pickyourown.org provides suggestions of where and when to go, as well as tips on canning, freezing and cooking with your bounty. Bon appetit!
