Welcome to the board. You will find a lot good information and honest opinions here... and some of these folks are a real hoot! Argentina huh... cool!.. I'll have to pull out the map and check it out again. That's one of the things that makes the board so cool. You can exchange ideas and info with divers all over the world. Divers are very friendly people...sort of a "brother(and sister)hood of divers"..
