I come to the Mob Museum as much as possible when I am in Las Vegas. It is truly amazing to see the exhibits that are authentic and in great condition. It is awesome to sit in the same room that the Kefauver hearings were held. If you were a Federal Law Enforcement person, you will surely note and appreciate the authenticity of the exhibits. I agree that the museum will take at least two hours to see and longer to truly appreciate the depth and number of exhibits present.
