Tried to talk my boys into the zoo for the Dinosaur exhibit.
@Dragonlovermom :
If it's the same dino exhibit we saw, it is for little kids 3-9. I think I recall you saying your kids are older??
The Houston Museum of Natural Science has an absolutely wonderful newish paleontology hall that all ages will love. It takes you from the absolute beginning of lifeforms, has tons of dinos with corresponding murals depicting how that dino lived, and ends with an exhibit of the history of the first humans. It is fab-u-lous!
