If you're anywhere near Southern California this time of year, and you're wild about flowers, the Flower Fields, in Carlsbad, are a must see! I must mention, if you like to shop, they're located right behind the Carlsbad Premium Outlet Mall, so you might want to stay a day or two.
As for the flower fields, I'll let the flower photos speak for themselves. Here's the website, address, and phone number. If you do visit, let me if you enjoyed yourself. I'm sure you will.
