My specific illustrative examples are just that. I'm not a lawyer and my case may not be constructed as well as it could be. I am however a passionate dive professional with above average PR and marketing knowledge, specifically with regards to new media. I'm not sure who Pete Lindquist is though, or how to contact him.
Having travelled and dived and worked in diving in several countries I believe I am in a position to comment and it's really not the petty bickering that irks me. As others have pointed out, it happens the world over. The difference it seems is that in Michigan the protagonists' overall standings in the bigger picture of things aren't particularly great to start off with. They're fighting themselves down the lower portion of the ladder rather than helping the Great Lakes region as a whole, and themselves within it, reach greater heights.
I'm obviously unaware of who you are or what you do but as a diver you must acknowledge that it would be a little disconcerting for a newcomer to peruse some obvious sources of tourist information and find them hopelessly wanting with regard to scuba diving.
Individual shops may well be doing their bit but times are hard, money is short blah blah blah. So why the tendency towards infighting and no concerted effort towards a Lake-wide promotional campaign?
I'm not sure what hard facts exactly I'm able to provide. This is a subjective area and one in which I would happily be proved wrong.
What I can say is that there is no mention of scuba at all on the front page of the state tourism website. The MUPC website is great but it's seriously under-supported and itself under-promoted (or, in my expereince, not promoted). Previous attempts to provide a central source of MI diving information have fallen by the wayside. As someone above mentioned, a quarry opens up in Michigan but is hardly supported at all. No one from the Great Lakes had a booth at DEMA 2007 and, to my knowledge, no Great Lakes advertising has surfaced in the national scuba press, despite several articles being written nationally and internationally in recent months.
I'm not greatly into the idea of an Oriskany-equivalent, given the proliferation of wrecks in the lakes already but if someone can raise the funds and support required to do it with such opposition then surely the entire industry can do itself a favour and do what is required to <insert water-related pun>.
