This 01/01/1991 video was a dive we made during the trip that I proposed to Sue. If memory matches my dive log the ship is the "Duane" in 90-120 feet of water off Key Largo. It was my 143rd logged dive and Sue's 8th. The dive video is basically unedited. It is one of the rare saltwater dives where both I and Sue are in the video together since Bill Ray was shooting the video.
In another dive on this same trip I was chasing a barracuda with my video camera along the port side of the boat heading towards the bow. Sue was heading towards the bow on the starboard side exactly in parallel with me. Well, she, I, and the barracuda met at the same time as I chased the distraught barracuda inches past Sue's unsuspecting face. Her eyes said it all as they grew larger than the 5' barracuda's teeth. The video is about 17 minutes long. But it's a nice sample of deeper saltwater diving. Lots of fish, a nice upright, intact wreck, clear water, and easy diving with minimal current at the bottom. The trick with casual wreck diving is to get around and see what you want to see without kicking up a bunch of silt. From the video you'll see that Sue did as well as anyone.
The music is from Synergy and yes I still do like it. It really grows on you after about the 4th hearing. Synergy is really one guy from the 70's who was "out there" (as was I) in recording electronic music. I met him (Larry Fast) while playing in Galesburg during that era when I was using 13 electronic keyboards on stage playing various rock 'n roll and progressive styles. We had a nice chat, though I don't remember any details.
