Doc Intrepid:
I don't know about that. If you have an interest in fresh water fish (I do) quarries can be some of the best places to dive.
We get some great vis and some really bad vis but generally pretty good if you can get there when there aren't too many other divers since they are almost always the source of the poor vis.
And as you saif they're good places for "some" of your training. In driving distance we have shallow quarries and some all the way down to 350 ft deep which comes in very handy.
