The town of Roswell in south-east New Mexico has become the focus of UFO and alien hunters from all over the world every since the 'Roswell Incident' in 1947, when an alien craft purportedly crashed near the town leaving surviving extra-terrestrials. Conspiracy theorists believe government authorities deliberately covered up the crash.

The incident is highlighted at the International UFO Museum and Research Center in Main Street, alons with a large collection of UFO memorabilia and artefacts. The museum also features a worldwide UFO sighting map and a comprehensive library. Roswell itself is just as UFO-crazy, and you can eat at UFO-themed cafes, and buy just about anything you can think of with an alien on it.
