My idea of a perfect weekday/end morning? Grabbing a cup of coffee, and heading over to one of the many Farmer's Markets stationed in various cities throughout Orange County. I find absolute bliss in meadnering up and down the aisles of a Farmer's Market; perusing through the gorgeous hues of veggies and fruits, shopping for fresh produce and flowers at amazing prices, and the best part? supporting local farmers and vendors!!
I was researching locations for other OC Farmer's Markets and stumbled upon the Orange County Farmer's Markets and the Orange County Farm Bureau. The OCFB site is a great resource; providing information and maps  for 'Certified Farmers' Markets'.
What does it mean to be a 'certified' farmer's market? "genuine farmers sell fruits, nuts and vegetables directly to the public. Every farmer who sells at a certified market is inspected by the county agricultural commissioner to make sure he/she actually grows the commodity being sold" (OCFB).
Here are a few OC Farmer's Markets (OCFB and city-sponsored/certified) near me that take place throughout the week that I have been to or would like to visit soon! I'm definitely going to be picking up a few bouquets of flowers for my mother and grandmothers this Mother's Day!

Enjoy your weekend!
