I fly fished off the jetties in Nuevo Vallarta a couple years back, caught several species of jacks and mackerel, nothing over about 16-18". I gave them to the locals who were handlining and not catching much that day so we were all great amigos by the time I left, they gave me a cold beer in return, it was a great time. If you go out the point toward Bucerias or Punta Mita I heard you could catch rooster fish in season, but that is more in the summer I think.
Never argue with stupid people, they will drag you down to their level and beat you to death with experience. --Mark Twain
