I use to live in Concord CA, I would tell people it is in the Bay area, not far from San Fransisco, Imoved out of there about 9-10 yrs ago. We now live near fresno/Hanford. A lot less expensive for us. I'm sure their are plenty of yorkie dog owners you can find in the dog parks. A lot of people don't know about yorkietalk, so tell them about this site. You will like it here, their is so much good stuff on YT that in can get a little addicting at times. So have fun
