Yes, Jeremy, it's a constant battle of good and evil. And I, with feet in 
both worlds, have to walk the fine line or suffer castigation.

Here's how the thought process works:

"Hmmmm, who's this guy over here? Oh, no, he breathing the long hose! he 
must be one of those goddamn nazi hogarth fanatics, where's my knife! But 
wait, he's got a computer so he can't be all that bad! Waaaait a minute, 
where the hell his bungies!?! Why I oughta.... Oh, he has a neoprene 
drysuit, hew! had me worried. Wha, whaaaat? What's that, a fucking cave 
light?!? Why that no good, rotten...."

Anyway in the sea of pony bottles, bungies, stuffed hoses etc. etc. I 
still would have been easy to pick out as the NE DIR rep. I'm getting 
there, Jeremy.

One thing that was interesting, on my support dive of the hard-core guys 
who did the 300' Washington dive only a couple were fully DIR rigged but 
NONE used dual-bladder wings. Are they out of touch or something? Or do 
the vet's realize what useless POS they are? Hmmmm.

I also noticed another item, "poor man's argon", i.e. use your nitrox 
stage to fill your drysuit rather than the trimix in your back gas. Never 
thought of that. I guess with cavers leaving stages you could not do this 
but with wreckers taking their gas with them...
