I did this hunt in 2015, was a lot of fun. I saw a stag, not where they are usually expected, but flubbed it. That still haunts me. Not much to add besides what has been said already. Call the local bait shops and ask for guide recommendations to ferry you over. I scouted the finger roads over on the north east side that dead end. You could smell them in the closed area but not much other sign over there and it took a lot of my scouting time. They feed in the freshwater sloughs, so focus scouting efforts around those. Bring waders and watch for alligators. Pack your stuff in storage totes. No running water on the island. Hunt time ends early, use the afternoon to bike around and scout. Definitely bring a bike.
