Buying helmets in the Bay Area: Any store recommendations?

[Darringer, Chris]

Hello listers,

I would like to buy a helmet to use at the upcoming Virginia City hillclimb
event (a clear warning sign that my Quattro club event habit is turning into
an addiction...)  

I was hoping to find a place in the Bay Area where I could try a few on for
sizing and comfort before buying one.  Does anyone have any store
recommendations?  

Thanks for your help,
