I have been checked on Truman and asked to see that my extra rod was labeled. The agent didn't actually look at the number close enough to know it was mine but wanted to see them labeled.
If an agent treats poles like a trotline or jug any fish you catch on your line or jug with your number goes toward your limit. So if all rods are labeled with one name/number they may all legally count toward one persons limit. Not for sure just a thought.
