It's cool that you can go up one of the towers (west side). What a view. As you walk further into the exhibit area, they have some old photos of events that took place there. There is an American flag as you enter and a cafe with snacks and coffee as you walk in further.
There are vehicles and tents to see as you walk in and a small museum with a wealth of knowledge inside one of the structures. You can see how an office and their living situation looked. I liked the dimensional map that showed the surrounding area. It was even more powerful to be there with people who grew up in the area and told us their view of the history that took place here.
At the very back, you can look inside the helicopters. If you're in the area, I recommend stopping in for a piece of history that's not in one of the usual places. Entrance is free.
