I have seen the warm water temps within 7 miles of Ocracoke inlet several years back. I have also seen a Nat. Geo. special on schools of tuna that stay just offshore NE of Cape Lookout . In fact a record Bluefin was caught on flyrod that was recorded on the Spanish Fly show .They were recording a show aboard Capt. John Jenkins boat when the call came thru that a potential record was hooked up . They motored over and videoed the event. I have seen it on TV , it was a monster Bluefin.
