Ok so they are trying to rename it again. They tried something like Harrahs North San Diego, but that didn't work. I too will just refer to it as Rincon. I think they still need the Rincon indians to have a casino in California don't they?
I live in the Northridge, Canoga Park area of the San Fernando Valley. "CSUN" is a University in Northridge. There was a big push to make the university more appealing to out of state students by calling it California State University at Northridge and not "CSUN". To us locals, it will always be known as CSUN.
