National Aquarium in Baltimore
As sad as it might be, the concept of the aquarium is slowly beginning to die out. The original idea was to present a museum of aquatic wildlife that people could walk through and see creatures that they have never seen before. While that is always a fun concept, once you have been to one aquarium, you have seen just about every creature that all the other aquariums have. After a couple of aquariums, you have had enough to last you a lifetime and have no desire to ever see another. Fortunately, the city of Baltimore in the historic state of Maryland has foreseen this issue and taken steps to insure that every visitor will always want to come back to their own esteemed National Aquarium.
