Here in Colorado we are totally land locked by a long shot, but have a lot of people with disposable income. Colorado also attracts a lot of people who like to play, and the combination causes a number of things to happen in reference to SCUBA:Hoppy:Thats scary ! Instructors who don't know how a bp/w works ?
We have the highest per capita SCUBA divers in the US, despite being land locked.
We are almost strictly recreational divers, mostly flying to Cozumel to dive once a year.
So, almost all the students are strictly recreational, so the shops are strictly recreational, so the instructors are strictly recreational (and have to wear the shop's recreational gear in order to teach) so no shops except one in the entire state know JS about anything even slightly technical.
We have instructors that do way more teaching than diving for fun, so when they tell you they have 1000 dives, what they really mean is that they've done one dive a thousand times, kneeling on the bottom, teaching students to keel on the bottom, who go on to be instructors all the time kneeling on the bottom.
Most shops are high volume schools, teaching a lot of instructors.
The instructors teaching the instructor wannabees have only done that one dive a thousand times as well, and don't know how to dive very well.
The new instructors learn what they're taught, which doesn't include how to dive well (teach well yes, dive well no).
For this reason and given the volume of students, I'd hazard a guess that Colorado has the highest number of bad divers than any state.
There's only a few of us that engage in what we fondly refer to as "Colorado Mud Diving."

And the whine: Because of the high demand, you rarely find anything one cent less than full retail. Colorado: Home of the $250 AL80.
