I've had chances to go to it in the past, but always found other shit to do. It was in Vegas, it was in Cleveland, it was in Pittsburgh, it was in NYC. But I either didn't really want to spend 24 bucks to see taxidermied people in odd positions or didn't have the time. But, I was in the Columbus science center this past weekend and they had a member price of 6 dollars to go see it, so I couldn't pass it up.
It was actually very cool. Not the actual deceased people in awkward poses, but the display cases in the center of the aisles that had all the different organs and body parts seperated. You get to really see what a diseased liver/lung looks like. You get to really see what the testes look like. Even the small inner ear bones and parts are there for display. There was an entire subsection dedicated to the brain and it had different brains in different various states of age and health. One of the coolest side exhibits was the human face cut off, so you could see the sinus cavities that lay behind it.
I guess there is a creepy factor involved in charging people to gawk at human remains, but it is presented in such an educational way, there is no denying it's benefit to individuals that go.
