This is a difficult review to write.
The exterior of this building is impressive. The interior auditorium is very nice. Lincoln's Gettysburg Address above the stage is inspiring. I can see why this auditorium is so popular with graduation ceremonies. So why do I give a 2?
The museum part of the attraction is disappointing. For $10 for an adult you get to go around the the exterior of the auditorium while still inside the building and look at these display cases that have rather routine military artifacts in them. I love military history and have seen far better exhibits. I was bored with my tour. This place needs a curator to better display what they have and more importantly add to it.
At present I cannot recommend you to pay $10 to view what they have and while the auditorium is nice to walk into its not worth the admission fee by itself.
I wish the museum was far better.
