The National Aquarium in Baltimore is one of the highlights of this fair city--they have a wonderful assortment of fish to entertain the young and young-at-heart for hours upon end. The Aquarium has many wonderful exhibits, including a wonderful dolphin show, a display about sharks, and one on the rainforest. Additionally, they are just completing a whole exhibit on the Australian outback. Fridays after 5--admission drops to just 7.50! Only downside--it gets a little crowded then. But definitely worth checking out.
