I was really impressed witht the Cell on my last trip to Denver. I went to the Art and History museums and sort of stumbled upon this little exhibit. Reasonably priced ($5 for student), I decided to check it out. It was really interesting. They had an actual piece of steel from the world trade center which was really powerful. I also loved the informational pieces about children in terrorist organizations, how terrorist groups are funded nad how countries balance freedom and protecting people. I thought it was really thought provoking. It only took me about an hour to go through the exhibit, and I probably could have gone faster if I had been on a time crunch. As a museum lover, I really thought the exhibit offered a new and different take on the traditional format. I loved the high-tech stuff and was impressed by their courage to take on such a difficult subject. I highly suggest visiting.
