What are some good websites of horses that need to be adopted?

No Petfinder please. I am looking to ride this horse as well. Oh, and it needs to be in Sonoma County, CA. Horses for sale and adoption.
Sorry, I ride Western and I am looking for a good all around horse. I want to go into barrel racing or reining, but right now I’m just looking. I want to look around a lot before I decide on anything.

I have found horses on equinenow.com, craigslist also lists horses for sale and you can pick an area close to you.
