Well, here's my report. We got there around 2:15, and it took about 45 minutes to get in due to length of the line. They had about a dozen tanks filled with water, and the building itself was cleaned up nicely. I heard the girl with a clicker tell another volunteer as I passed that they had over 3300 people come through so far, and there were probably a couple hundred people behind me.
While the building is nice, I would think that if it were operated as a business, there would have to be expansion to garner enough interest to bring in paying customers. I was looking at the building, and there looked like there was enough space for a pretty big addition on the left side of the building. After I win the Powerball tonight, I'll have to look into it

The other thing I noticed was that donors were recognized with a placard above the aquariums. Several were marked "Donated by The Fish Pimp Aquaculture Enterprises"
