Well, I've been trying catch that damn fish in Pokemon.  I'm using the go from square to square while surfing on route 19.  Each square I've fished at least 5 times with the old rod.  I'm about halfway through the entire area after a bout a week of on and off trying and still haven't found it.  It supposedly shows up in 6 squares that remain constant as long as you don't change the word in that island town.  Has anyone caught one that has a better technique?  I'm really getting frustrated.
