What do they mean you can add it to your Drivers License for free ? No $50 fee ?
Yes, it is good forever in LA. You can also apply for a lifetime in MS once you meet their residency requirements
So the La is still good when you're not a La resident anymore?
Once you have been licensed, they will add the endorsement to your license card, so that you don't have to carry two separate cards to prove that you are licensed to both drive and hunt.
