I don't think you are dealing with a tough crowd, it's probably because your question is very broad. Quail live all over the Yaki Valley, find cover, food and water and most likely, you will find quail. It takes some time in the field to narrow down the spots, but that area has some of the best quail habitat in the state, it shouldn't be hard to do, even if you are starting cold.
Look for public land with the above criteria and pound it...you will find birds.
