Best 4th of July celebration in the bay area?

I don’t normally celebrate the Fourth of July, but I figured the country’s 250th anniversary is a once-in-a-lifetime event and I ought to do something for it.

I was originally planning to head into SF for the Golden Gate Bridge fireworks show, but from what I’ve been hearing from locals, and seeing in the fog forecast, it sounds like there’s a pretty good chance the fireworks will be heavily obscured.

So now I’m looking for an alternative somewhere else in the Bay Area. Any recommendations? Are any cities putting on a particularly big 250th anniversary celebration that goes beyond the usual local Fourth of July festivities?

I’m coming from San Jose, but I’m willing to travel around the Bay for something worthwhile. Or maybe I can stay in San Jose if the city is doing anything big.

Any ideas?
