Hmmm...The Monteray Bay Aquarium is top-notch and well worth going out of your way to visit. I live in the Minneapolis/St. Paul area of Minnesota an the Mall of America has an aqurium called Under Water Adventures. By itself it is okay, but spring the extra $6 for a "behind the scenes" tor and you will get your money's worth. It is an hour long in-depth tour that covers everything from conservation, to diet, to QT, to general husbandry. They also have a very large and nationally known shark and ray breeding program.
Some people are like slinkies...they serve no real purpose yet can still bring a smile to your face when you push them down the stairs!:p
Have a great day! Brian
