if the fish are biting, 2 is all you need. if they AREN'T biting, even 1 is useless.I grew up on a 2 rod limit. Moved here and still pretty much just use 2 rods. I fish alone and that's about all I can handle when the fish are biting.
It was repealed probably around 1990I remember when there was a 3 rod limit. Don't remember when they changed it though.
