Dave...Met you in Acklins...
Cheeca is the best place in the middle keys. Florida Keys Outfitters in Islamorada is a great shot. They can set you up with a great guide. I fished with John "Mitch: Milchman after a completed the saltwater school run by Sandy Moret from Florida Keys...They are a class act.
Make sure to grab a bite at Morada Bay. One of my faves. My wife continues to ask when are we going back to Cheeca. Too bad I am stuck in AZ.
