The Way they do it
The way they do it in Mexico is use a coke bottle or something similar for a reel. Wind the line around the bottle, hold the bottle by one end, and point it where you want to cast. Cast the line like you would throw a lasso. Gives you something to hold on to, very important when a very big fish is on. No way most hands could stand hanging onto just a line with out cutting them or slipping with much of a fish on. It also keeps the line in one place, and no tangles with your feet or someone elses. As you "reel" in, hold the bottle, and wind the line around it. It's an easy skill to teach yourself, and would be suprised if you didn't see some natives doing it down there. You can even buy a rig like this in Mexico, but it comes on something resembling a popsicle stick, which doesn't work very good for me. An old fashioned coke bottle seems to be the reel of choice in Mexico.
