Farmdale is north by north east of the landing. Roughly one mile before the landing turnoff. It's a left turn at the fire station as your heading towards Mexico beach, and behind the tree line in that ajacent clearing.
Side note: We went floundering in CIS last night, and did reasonably well fishing at the first cutout to the pass after the white posts. Killed 3 right there at the east side of that cut out with the flounder sitting right on the ledge to the drop off (staying inside the sound). Also, using a 3" new penny ... boated a couple of nice spcs. No worms in them either.
Upon returning to the landing, we were greeted by two friendly TAFB MPs who advised us that the landing is closed to the public 1 hour after dark, and that if we wanted to stay in the sound, we'd have to relocate our vehicles to Mexico Beach.
