The Tennessee Aquarium lets girl and boy scouts and their families in for half price on certain days, so we took advantage of that and had a great time! My favorite was the otters - they did not disappoint. They played and swam all around. The girls liked petting the sturgeon and sting rays. Lera loved the penguins best. She used a little stick she got at lunch and lead a penguin around for about 10 minutes. It followed her stick all over the place and Lera got a big kick out of it. I love learning about all the beautiful animals they have there.
