Did my share of freshwater fishing for bass and whatnot, but my fondest memory has to be when I was in Diego Garcia for a year while in the Nav. DG is an island basically in the middle of the Indian Ocean, with a very sharp dropoff not 300 yards from the beaches. We had a choice in "boats" if we wanted to fish that way - either an actual old WW2 landing craft that would take 20 at a time for around 50 half day/100 whole day bottom fishing for cod, sweetlips, etc, or 65/130 for five people trolling for marlin, wahoo, tuna, and whatnot.
And one of the best past times was throwing a bait off one of the island's "points" with the cooler full of beer for a night. Catch all sorts of beasties, but the one fish with serious bragging rights was the "GT" or Giant Trevally. I remember just a 25 pounder taking me a good mile down the shore before finally landing it. But the record was over 140 lbs, with 50 to 70 pounders not uncommon. Good eatin' too!
Here's a pic I stole... these guys were BEASTS...
