Area 51 Birthday Bash, May 27-29Happy 50th birthday, Area 51! Long regarded as a land of covert testing and aliens, Area 51 (a.k.a. the Groom Lake Facility) was founded in May 1955, and the conspiracy theorists haven't been quiet about it since. Although it's a testing facility for classified, or "black," aerospace projects--graduates include the SR-71 and the F-117 stealth fighter--most visitors these days go for the thrill of being chased by the security guards, the so-called Camo Guys. On Memorial Day weekend, Area 51 enthusiasts will gather for barbeque, camping and impromptu talks about the site and its checkered history. See dreamlandresort.com.
