I just returned from visiting PA and visiting this museum. I have to say that this museum is outstanding. The day was hot and muggy and I wasn't sure if it was worth it to make the trek to see this museum. Boy was I surprised! This museum is huge and offers lots of rare items to look at. It took nearly 2 hours to tour the whole museum!
This was my first visit but definitely not my last. Check it out whenever you're in the area.
