An event for fans of a Steven Spielberg classic.

FOX's Rich Denison reports:

UFO enthusiasts are preparing to gather in northeast Wyoming in a few weeks.

They're heading to Devil's Tower, the 800 foot tall ancient volcanic core featured in the movie 'Close Encounters of the Third Kind.' The event will mark the 40th anniversary of the classic science fiction movie's release.

The the first Devil's Tower UFO rendezvous will be held at the site from the 14th to the 17th of next month. While there's no guarantee of alien encounters, organizers say their will be a parade, live music and a barbecue cook-off.
