From another member since 2003. Points: 24/7 access to all three quarries, very clean, over 90 feet deep, very nice divers, great training, vis is great right now, lots to see underwater, price for a year membership is less than two Blue Stone trips, very trustworthy divers. Bad points: parking is getting harder and harder, sometimes too many classes, water temp...it is cold...just face the fact that it is cold, can't fish any more, NO SOLO DIVING allowed and that is about it. If you are needing a buddy, you might would like to check out NC divers site, join the quarry on FB.
We did a trimix class diver yesterday...93 feet for 71 minutes. Vis was great and you could see the entire crane from a distance of maybe 20 feet. You did not really need a light IMO.
