It doesn't matter how Many rods you fish with, as far as I am concerned. I go fishing for the enjoyment of just being on the water. If you use a bunch of rods that means that you get done fishing quicker. I am not into spider rigging all that much. I enjoy the battle of just figuring out what and how they want dinner. I will at times set a couple of rods in a holder on each side of the boat like P4P does and just push the baits around. I mainly do this when I have someone in the boat that isn't to adapt at catching and have them drop the line over the side of the boat and will pull them through the fish. If I have a couple of guys in the boat I will do a side drift and let the lines out the side and use the Trolling motor to stay on the contour line, or creek channel which ever we are fishing.
In Mn you are only allowed 1 pole to fish with. When I fish the boundary waters up there I will buy a SD license to fish with because you can use 2 poles there. EB
