Kind of a funny story...the guy wanted to build the museum, but the city would only let him if he developed more of the land and built a mall for the city.
So, there's a mall there...that's pretty much empty as it's 20 minutes away from a NICE high-end shopping area of Walnut Creek. *laughs*
I've never been there, so I don't know what it's like. I was going to check it out when they had a traveling Deusenberg exhibit, but it was around holiday, and I work retail...so I never made it.
