Kayes Music Scene in Northridge is also about 30 minutes away. They carry Kanilea but mostly lots of Kalas, Islanders and Ohanas. But they do have about 200 ukuleles on the wall. Also the Happy Little Ukulele Club of Thousand Oaks meets on the first and third thursday of the month from 6-8:30 at Harry's Omelette Shop. I also think that Brian Beverly and Jason Iriguchi build in or around Ojai which is near Ventura. Also Jason Wolverton is in Orange County which is about 90 minutes away, and John Kinnard is in Fallbrook (San Diego County). They also have some high end ukes at Artisan Guitars in Santa Monica. There is also Island Bazaar in Orange County which sells ukuleles and has a lot of metopes at the store.
