I am a huge fan of The X-Files. I know the show isn't necessarily linked to Roswell, but I've become obsessed with anything UFO related. So when I had to drive my daughter across country, I had to stop in Roswell, NM.
In 1947 a balloon crashed in Roswell, NM when the Air Force was flying a weather balloon as part of an experiment. But in the 1970's conspiracy theorist came out to inform people it was not a weather balloon. Their theory: a UFO landed and the government tried to cover it up. These theories became so popular making Roswell known for one thing, UFOs.
Next stop, Roswell, NM!
UFO crash site! This is where the supposed UFO landed.
