It's worth a try. A lot of the displays have neglected for a long time and the Army stuff seems to be more neglected than anything else on the premises. I don't even know if we have the Vietnam troop truck anymore. I never really pay much attention to the "front yard" of the museum.
We even had a caboose at one time and then we gave it to some music museum (I think) that went under shortly thereafter. Now, it's scrap metal.
