A few weeks ago I was able to go on a tour of an Underground Salt Museum. It was actually pretty fun and I was able to see a lot of interesting things. The ride down in the double-decker elevator was completely dark and they told us that we were traveling at about 7 miles an hour. Once we reached the bottom we got on a tram and were driven around the mining tunnels first. We could actually see how the pressure from the walls was pushing the floor up and making creators by the walls. I don't remember the technical terms but it was pretty cool to see. At one point in the ride they stopped and turned the lights completely off and you could not even see your hand 1 inch from you face (I tried :P ). Then we stopped by a pile of salt rocks and got to pick out our own rock to take with us. Of course I took one too but now I have to find a place to display it. Displaying salt...hmmm. Once the ride was over we were allowed to roam in the actual museum by ourselves. They have a whole bunch of different things to look at from old vehicles (that are rusted) to pieces of mining equipment, newpapers dating back to Abraham Lincoln, & different items from movies in Hollywood (I got to see Mr. Freeze's outfit :) ). Once we finished looking at the museum we rode back up in the elevator and that was the end of the tour. It lasted about an hour and a half to two hours so I think it was worth it. So if you ever get the chance to go to an Underground Salt Museum then go.
