Alien lovers around the world are congregating in Arizona for the 20th Annual International UFO Congress -- fielding a mixture of the cute, the critical and the downright crazy.
Apparently, the skies above Phoenix are a hotbed for alien activity. If you don't believe in extraterrestrials, you might start to after a visit to this convention, held all week at the Radisson Fort McDowell.
Skeptics may want to prepare themselves for some eye-widening ET yarns.
"I think everybody should be interested. Isn't that the biggest story in the world? Visitation from an extra terrestrial civilization?" said Jeff Willes, a skywatcher.

Cynthia Crawford is a sculptor from Apache Junction who makes statues of extraterrestrials. She says people who buy them are often visited from alien lifeforms.
