I wish I had taken more pics at the Georgia Aquarium, specifically of their protein skimmer room, and pump room for their Ocean Voyager tank (6.3 million gal.). It was almost unbelievable. Those 6" swing check valves in your pic are $2K/each, alone

That business you have going on at the zoo is nothing to balk at! I was/am amazed at everything you all had going on there.
I was especially jealous of those kids you had there that got to work with you all FOR SCHOOL! if I had had that oppourtunity when I was their age. MAN! don't know how lucky they got it.
