I have been a little busy for a while... A little while back there was a dupont bridge span put down. There Just recently there were two more Dupont Bridge Spans put down. They were put down about 1800' apart in a square. The fourth corner of the square being the Mac Reef. If you had a scooter, or maybe just a rebreather this would be a great circuit to dive... I'll go out there next week and get some pictures of them to post...
