Greg -

I'd be interested to hear more about the tech diving scene in the midwest in 1990 (since Nitrox would've been considered "tech" back then).  There's so few people on this list who have been diving the Great Lakes that long - it'd be great if you could share some of your diving experiences from the early 90s.

The guys that were prominent in the Great Lakes since the 60's - 90's probaly don't have computeres.  I wouldn't even consider myself actively tech until mid to later 90's.  It has been quite the evolution.  and I really can't hunt and peck that long on a key board - but I can babble forever.
Black Magic in Libertyville was the first shop in IL to offer any formal training and fills. In thinking a little harder I will say 1990 is off a little should have been early 90's.  But even into the late 90's Nitrox was hard to get in IL.
