Look on tdtdivers.com there is a trip to PCB on the weekend of the 21-22. There are several divers going from the North AL area including me and my wife. All of the details are on tdtdivers as well as costs. I am a dive master. I know another of the divers is an advanced also a doctor with close to 1000 dives. Mosr of the divers on the trip are advanced or above. Good Luck.
