I think the location is what is going to be most critical. Pretty much ever city is an hour away for me. So i'm in the middle, i have the least to worry about. But if you move it closer to SJ, then everyone from sacto has a longer trip. Move it north, SJ has a longer trip. So with out alot of cars, a drive over 1 hour isn't really worth it for anyone. From what it looks like SF is the best location for everyone, but if everyone doesn't go, it's not really the case.
