Al,
  Heres some info on Mukilteo State Park:
   1) State park is open to divers of all certitification levels
   2) The "500' slope" starts about 30 yards from shore.
   3) The slope runs down about a 45 degree angle and gets very deep real
quick.
   4) This site has a couple of 3' benches between 50'-80' that are home to
octopus and is well known in
        our diving community.
   5) Most  dive stores in this state have used this as a training site for
anything from basic scuba to instructor
        to mix,  but most use it for advanced class deep dives.
   6) Most divers up here in the puget sound don't dive below about 80'
because of sunlight penetration and
       significant reduction in marine life below this depth.
Having explained this I believe Garrett was responding to some idiots
blanket statement about taking students to dive sites where they could
exceed the depth limits of their gas is criminally dangerous. The words
"tunnel
vision" and "this guy doesn't live in the real world" come to mind when I
read statements like that.
     Air fills in the puget sound area run 4 to 6 dollars and nitrox is
about 8 to 10 dollars. You may get 10% of the divers to dive nitrox but I'll
bet you never get the rest to switch.
     I would not define the above slope as a "hard bottom" and the last time
I checked my agencies training standards there was no mention of a " hard
bottom" requirement.
