Arizona "Aliens Welcome Here!"

Arizona, the Grand Canyon state, was admitted to the union on February 14th, 1912. Six months later, the first beings from another world landed just outside Tombstone and proclaimed their peaceful intentions.

Eight months later, a different species from the same planet landed near Flagstaff.

A year later, quadrupedal aliens from another system arrived in Prescott.

15 months later, two related species from the "Dwistok" system landed in Phoenix.

And so it has gone for the last 70 years. New and different aliens landed every few months to two years. They would number anywhere from a few dozen to a couple of thousand. Most were well adapted for the desert environment, but a couple of species took up residence in the Colorado river and one bunch went off to live in a series of abandoned mines.

Now, in the year 1986, Arizona is home to 78 distinct species of extraterrestrial life. All are intelligent, but most abandoned or even destroyed the technology that brought them here. Interestingly, all of the aliens are oxygen breathers and can exist quite well on Terran foods, although "food" can encompass such things as limestone, used motor oil, and human excrement.

This high level of alien species has made Arizona THE tourist site on the planet, as well as the area with the largest amount of scientific research labs. In fact, Arizona makes so much money off of the aliens that there are no taxes whatsoever in the state and every 4-5 years, the state actually gives every citizen a check for a few thousand dollars.

Yep, in Arizona, they really love their aliens.
