Back when I worked for Reel-Time, I used to call Capt. Jeff Northrop for fishing reports from down that way; if your pal's involved in the business end of fishing, Jeff would probably know who he is. It's been 14-15 years, so I don't know how to contact him any more, of if he's even still in the area, but Jeff would be the guy I'd talk to. Or you could contact every tackle shop in the area and tell them you want to pay back the $1000 the dude lent you when you were in Mexico last year and lost your travelers' checks. Tell them you can't find his contact info and try to sound like you're drunk - that'll make the whole yarn more believable. Even if you wind up talking to the miscreant himself, he'll probably give you his name and address on the off-chance you'll send him the grand before you sober up.
