Yep, and I don't see where they have to be in holders,,,,,just the additional poles over 3 is how I read it.
The following is a quote from the Missouri Conservation.........
"Sport Fishing: General Rules
■MethodsYou may take fish by pole and line, trotline, throwline, limb line, bank line and jug line. If you use more than 3 poles at any one time, the additional poles must be labeled with your full name and address. Regardless of the method or number of poles, you may not use more than a total of 33 hooks at any one time. Hooks on trotlines must be staged at least 2 feet apart. Hooks on any type of line, as well as the line itself, must be attended every 24 hours or removed."
