2. Visit Early Works Children's History Museum with among other things, a talking tree.
3. Visit the Huntsville Botanical Gardens - there is always something going on there.
4. Visit Sci-Quest Hands on Science Museum. I haven't visited this one, but the kids seem to enjoy it.

6. Take in a Huntsville Stars (minor league) baseball game.
7. Ice skating
10. Burritt on the Mountain - a living, history museum

I only chose kid friendly activities. This would make an interesting meme. I challenge anyone reading this to list activities in your city (or the surrounding area).
