The living planet aquarium, while too expensive for it's size, is still a fun family day. I have been wanting to visit Discovery Gateway. The Bean Life Science Museum has a lot of stuffed wild animals and such and is free. I got my ideas from www.uvmag.com - click on the May/June magazine and starting on Page 46-47 (link at the bottom) there is an article entitled "99 Days of Summer". Have fun!
