My bud in Ventura/SB area has told me that these areas are slim pickins now. He says you're better off making the small pilgrimage to the LA area.
In addition to the two previously mentioned, there is Mission Liquor in the Pasadena/Altadena area. Good selection, a little pricey. They do have some good deals on some stuff and carry from the very low end on up (Lagavulin 30). K&L Wines recently opened up a store in Hollywood. Decent selection although a little difficult to get to.
As for Monterrey, you might get MikeyMad involved. I believe he has indicated that there are one or two near the aquarium. Also, you could make the trek over to the lower area and visit Beltramos or K&L. Beltramos has had Highland Park bottle single casks for them exclusively. Also, a Glenfarclas.
