This thing made the rounds, showing up on both Midcurrent and Moldy Chum… still, if you missed is somehow, here is a little vid about a couple guys getting into some pretty virgin skinny water somewhere near the Belizean/Mexican border (slightly on the Mexican side, it seems). Costa de Cocos lodge is down that way… I’m guessing it is nearby.
