Yep, I do see all kinds of mixing out here in CA. It's really hard to tell what's going on with all the different flavors...wait, are we still talking about pizza?

Seriously though, it does seem like there is a lot of mixing of the people out here. Throw in the confusion about Hispanic being a 'race' and it becomes even tougher to tell. I would guess in this study we're talking about people who self-identify as Hispanic.
