Mike takes every incident very personally... He does a better job than I have seen many other quarry owners do regarding notifying the divers of the hazards (depth,cold,etc.). He does everything in his power to inform the divers that they need to have their head screwed on right. He doesn't run a babysitting service!!!
Maybe instead of conveying that "...the place needs to be shut down..." the individual divers need to look in the mirror, park the ego at the entrance, practice the basics a bit more and dive within their training abilities...
EDIT...
.I believe that in this day in age it is too easy to simply blame the "institution" instead of the individual.... Example: McDonalds and the spilt coffee incident several years ago???
Ultimately, it comes down to the decision of the diver NOT Mike.
EDIT....
This is not intended to come across as hostile, only as someone who personally knows him and also knows how much effort he puts into making it one of the top dive sites in the Midwest and given the depth, one of the safest around.
Edits were made as some of the items were just recently addressed and didn't want to be redundant...
