I don't have a good feeling about the one day MX fishing license being temporary. I'm thinking that the online price increases in 2018 for an yearly MX fishing license (+$9 USD) and FMM (+$6 USD) weren't enough. Now, since there's a new MX government there'll soon be new rules to increase revenue. We'll see if continues to encompass U.S. Sport Fishermen. Here's a thought: The U.S. should reciprocate by charging foreigners (pedestrians and vehicles) a one trip fee every time they cross the border into the U.S. What a great way to pay for a Wall!.
