Keeping To A Space Theme,

I did not realised that when we are visited from space,

planet earth already has it's own Intergalactic Spaceport in the US state of Wyoming, it even has it's own runway known as Green River 48U, in 1994, the Green River City Council adopted the spaceport moniker as a tourism stunt, the idea was to welcome inhabitants of Jupiter who might wish to take sanctuary in Green River, when their planet was threatened by collision from Comet Shoemaker–Levy 9, surprisingly, the Federal Aviation Administration (FAA) approved the name change, the city is now looking forward to convert the spaceport into a proper airport to attract general aviation traffic that would, hopefully, boost tourism in the area, also I guess to insure that other planets inhabitants know that their trips to earth are also welcome, but there is one group of people who are not welcome, the people that keep stealing the sign!
