Try on your Giro Advantage 2 (size large) near Daly City?

I have an odd-shaped head (long from front to back, somewhat narrow on sides) and think my best bet at an aero helmet is going to be a Giro Advantage 2. Some Giro helmets fit me reasonably well, so I assume the aero helmet may work.
I live in Daly City, CA and can't find any place that sells them locally so I can try them on. Are there any forum members nearby that own a size large that I could try on? Much appreciated!
