This Croc thing hasn't caught on in SoCal. At Disneyland you see them occasionally on tourists (which you can spot with the bad suntan lines and different fashion from the locals), but for the most part Disneyland is free from Crocs. I never see them being worn on people at the malls, beaches, stores or restaurants of Orange County. The neighbhorhoods and commercial centers of Villa Park/Irvine/Huntington Beach/San Clemente and Laguna Niguel that I frequent are entirely Croc-free.
This apparently is a Midwest/East Coast thing. I'm sure there's some Croc somewhere in SoCal, but you sure don't see them much. I wouldn't even know where to buy them, and I was just at three major OC malls this weekend; South Coast Plaza, Fashion Island and Mission Viejo Mall. Never saw them for sale there.
