Tom, forget all of the other stuff -let's just look at the only part
that we can legitimately second guess - the use of narcotic mixes in
dive instruction or technical diving. 

   I have no idea who these divers or instructors are, there are always
a fleet of them on every boat, and none of them are from here. In fact,
I do not believe there is a tech instructor from this town.

below the aed of trimix. ?? - G
