Extraterrestrial Tourism really is considered a niche market, but it’s not really named properly as that would involve visits to other worlds. Roswell New Mexico is the best example of ET Tourism. For decades the city of Roswell has based much of its tourism economy on the mysterious crash back in 1947 that some claim was an alien spacecraft with aliens aboard. Most Roswell conspiracy theorists also hold that the US Government covered up the evidence of the Alien landing.
Now Roswell is stepping up to the Extraterrestrial Tourism plate with a new amusement park that will feature an Alien Abduction Roller Coaster ride as well as other Alien themed rides and attractions.
I just hope they give free parking for all the UFOs that are sure to land there regularly to ride the ET coaster.
