I am interested. I usually fish farther north, ie humbolt bay down to mendocino but would like to expand my horizons. It all depends on timing , work, etc. There are probably more lurkers like myself who would show but cant commit at this time. As for organization, the simpler the better. You do enough work already.
I would think anyone could come. Our immediate family includes those who are registered and who post but many people simply watch the posts. Both, to me, seem to be members of the larger family of interested anglers.
