Been to Half Moon Bay (named because of it's shape) 3 or 4 times. Unreal place to surf, any time of year. Never know what to expect day by day. I would doubt that those people who got a little salty yesterday were all locals. Mostly tourist get hunt the most up there. Or any where else along the coast.
Never have been in a tourney anywhere. Though one of the best is at Huntington beach, up the 5, from where I grew up. San Onofre, at times, can be exceptional. Go there or Carlsbad usually. Zuma, just above Malibu, can be good. Though too many want-to-be surfers from The Valley clog every thing up. A few guy's were bring the long boards back, last time I was up there.
