California has so many MSAs, and no, I haven't been to all of them.
Here, from the ca.gov website:

But the biggest ones I can think of off the top of my head that I have not been to are Fresno and Stockton, which I've only driven through on the freeway, but never stopped, not even for gas or a restroom break.
But that might change, though; hehe a few years ago my partner mentioned a Japanese garden that's in Fresno... we just might check it out some time to compare it with other Japanese gardens we've been to.
Ah what the hell. I'll list the California MSAs I've never been to, which includes ones I've only driven through and not stopped to explore (this list doesn't include the Micropolitan Statistical Areas I've been to):
El Centro
Fresno (only driven through)
Hanford-Corcoran
Madera (only driven through)
Merced (only driven through)
Modesto (only driven through)
Redding (only stopped for gas there)
Stockton-Lodi (only driven through)
Hmm, of the 29 MSAs in California, I've only not explored 8 of them.
