As you prob know, I was living out there for a bit and got to hit trestles a bunch of times. Personally, I never found that lineup difficult at all. Sometimes a bit crowded (surprisingly more issues with newbies than pros), but respectful and no hassle. Usually the biggest obstacle I had to getting waves there was my own kookiness.
I also like snaggles strategy. Whether it’s trestles or any other crowded break, I usually stake out a spot that isn’t necessarily right in the main takeoff spot (or I surf there on days when the crowd is expected to be light/elsewhere). And then I just wait for good ones to come my way. At trestles sometimes I sit real deep or sometimes kinda far out or sometimes head up the beach a bit – personally I like uppers better anyway. Folks there generally respect when you’re in the best position (rather than dickhead NY’ers that will paddle battle down the line), and I am always courteous and let people know right away whether I’m going or not. And if I am going, I effing go. If not, I let them know so it doesn’t go wasted.
I think a little wave knowledge goes a long way. Out in HI, my brother and I used to have a couple waves pretty wired. I mean we had lineups (triangulation kind) down to the nearest meter depending on size, tide, and wind. I always knew when the lineup (people kind) had drifted too far out, in, left, right, etc. We could also game the visitors (or crabs as we called them). But that’s team tactics which is probably beyond the scope of what we’re talking about here. I guess the point here is that nothing beats water time at a particular spot.
And generally I’ve found that CA surfers are a little lazy – no offense, it’s cool and laid-back. But a wave-starved new yorker sometimes tries a little harder. Things that I’ve noticed CA surfers dislike: current, dump&thumpers, long walks (no pave for skaters/bikers), stormy crossed-up peaks that haven’t organized yet. I surfed a bunch of headline breaks by my complete lone self because of the previous factors.
Lastly, I’ll say that while I really don’t like any hassles whatsoever, every now and then you just gotta assert and/or stick up for yourself. Most of the time with me it’s just out of principle, but I can also be a spiteful vindictive little bitch too.
