For the first time I'll have to take 4salts' side and also CFMs' opinion as well. I have a 5 year old son who has a punch card and is legal to catch salmon. I only run 1 rod with him in the boat because it just gets too difficult to handle everything. Rods, kicker motor, my sons' goofing around. He just isn't big enough to handle a rod without help yet. So on my boat, 1 rod.
On the other hand, I really don't have a problem with the state charging an extra fee for a 2 rod stamp. I do believe that is the way in California. It's just my opinion and not to be forced on anyone.
