Tour a Famous Oil Rig
Morgan City, Louisiana
"Mr. Charlie" was the world's first transportable, submersible drilling rig when it was built in 1953. (For a time it had a rival, "Mr. Gus," but Gus sank in a storm.) Mr. Charlie kept drilling until 1986, and was retired only because it had sucked all of oil that could be sucked out of the Gulf of Mexico within waters 40 feet deep, which was the length of Mr. Charlie's legs. The success of this rig made possible the entire offshore oil-drilling industry, so your opinion of Mr. Charlie will probably depend upon your politics.
Mr. Charlie was offered to the Smithsonian, but it didn't have the room to exhibit a drilling rig hundreds of feet long. So a museum was built around Mr. Charlie. Tours are given twice a day, and take anywhere from an hour to 90 minutes.
