I'm interested in this as well. I originally got my PADI open water cert in '92 (old scuba park at Lake Travis), but didn't do much with it until early 2000s, when the bug hit me again. The majority of my dives have been low visibility "swamp" dives, in Texas lakes, but I do have some dives in Mexico and Belize. I ended up switching to NAUI and got my nitrox, advanced, rescue (my favorite course to date), and training assistant. (was working towards DM) I've helped out with several OW, advanced, and rescue courses at Clear Springs Scuba Park and Lake Travis.
I enjoy diving the blue waters of the Caribbean, but my favorite dive (memorable) has to be 110' down at Lake Travis, in the pecan grove. It's kind of eerie to be in "Windex" clear water (but zero sunlight), and come up on old pecan trees, that far down.
Having a SIG for this, may be what I need to unpack my gear and get it serviced and my tanks hydro'ed.
