Here's what I can tell you in one word: Amazing. Two words: Must See or Bucket List. I've been there numerous times and always come away amazed. We used to go there about every year or two at Fantasy Camp.
Especially, fun was seeing their display dedicated to the Kingston Trio.
And, finally, when the brouhaha was happening between Bob/Bobbie and Mike/Josh over the contract, I was asked by both parties to act as an arbitrator. We were trying to keep the lawyers out of it. We reached a point where it looked promising and I wanted to get both parties together someplace to talk. I chose the MIM. I called the assistant director at MIM and she reserved the Green Room at the museum for us all to get together to talk things over. Keep in mind: both parties agreed to the meeting. Then, when I called Bobbie on the following Monday to give her the good news that we had a place to talk in a neutral setting, she informed me that they had talked to their attorney and he advised them not to meet...! And you know the rest of the story.
