I didn't even know the Tellus Science Museum existed until yesterday morning. After finding out that it had a planetarium, I decided that it would be a good idea to take Mom and Dad there for an impromptu visit. The place is actually very interesting. It's much, much bigger than I expected. It felt like there was more overall exhibit space than at Fernbank in Atlanta. I don't know if many other people know it's there either since it was mostly empty. If you're looking for something educational to do, I'd say it's definitely worth a visit.
Dad really liked this very large dump truck. It's tough to tell how big it is from the picture, but imagine that each tire is about the size of a small car.
