Never thought about it before. I suppose by the letter of the regulation a rod should be marked, but I think the intent is to mark devices not under the control of the angler. If there are more than six, or they are left unattended the warden needs to be able to identify the angler. Hard to believe a rod in hand would be treated the same way since it's pretty clear who the angler is. Guess I'll find out some day. I use trapping tags on the tipups, a guy named Larry Finch makes them at a very reasonable cost.
quote from the Anglers Guide "The name and address of the user must belegibly stamped on or attached to all devices." I see no confusion.
