Balboa! Always pretty clean, fairly easy parking, friendly people, never too crowded. Easy to get to.
But most of all its because if familiarity, i know which spots for particular fish, and the bait spots.
Also like the railing much better here than Newport or Huntington, good height, not too high or low, and i like putting a foot under the bottom rail as i cast.
I also like being able to watch the current as it hits the wedge, with Catalina in eyesight (when it isnt cloudy). And if the pier isnt producing, i can walk across the street and fish Newport bay under the boats for some bass.
