The AJ's are going to be in water 200+ feet generally. That's about 40 miles out. Blackfin might move in that close if the water cools down a bit. Wahoo are generally in deeper, blue water. A ling (cobia) is always possible.
His post made it sound as if he was staying closer to shore and it doesn't sound like he's got the tackle for AJ's, tuna or 'hoos. Big AJ's will make a man out of ya'.
