Government officially acknowledges existence of Area 51, but not the UFOs

The last time I visited Area 51, it didn't exist. But as of this week it does. Officially. For reasons unknown, the government finally has admitted that Area 51 -- the Shangri-La of alien hunters and a sturdy trope of ­science-fiction movies -- is a real place in the Mojave Desert about 100 miles north of Las Vegas.
