Saw an article about fishing for corbina near San Diego, and the guy mentioned catching other species such as halibut and surfperch on the fly... I might be in San Diego early April and I know the corbina won't be there, but will there be surf fishing for other species, and if so, any tips? Fly fishing for halibut intrigued me, but I have no idea on how I'd set out about doing that. Any tips?
Thanks!
