Art, these people are doing so many stupid things that figuring out what
kills them is like trying to figure out what killed people at Hiroshima.
Get real, these people are so stupid, and so full of bull that not only
is anything they say ridiculous it is lkely not even true.

Here are the facts: these idiots have made Nightline and the front pages
of several newpapers as well as attracted the attention of the Coast
Guard and legislatures, and you want to talk about "furthering causes". 

Tell me one thing this guy did that was NOT stupid, and did not
contribute to his demise? 

Here is what needs to happen: the Coast Guard needs to start charging
commercialo rates for time wasted dealing with these idiots. I think I
need to call them, and make a few recommendatoins. Now that would be
"furthering the cause" - the cause of these guys not ruining it for
everyone.

Trying to talk any sense into any of them is impossible - the obvious
and the basics are flying right over their heads. By the way, if Wrolf
Courtney is out there, could you send me your email address so we can
get the Coast Guard accident reports to you for posting on your website.

ART, THES ARE NOT DIVE ACCIDENTS, THEY ARE ASSISTED SUICIDE.
