UFO enthusiasts converge on rural Nevada for a pilgrimage of sorts to the US military installation known as Area 51, long rumored to house government secrets about alien life.

Some residents worry about their community might be overwhelmed by unruly crowds turning out in response to the viral Facebook invitation to "storm" Area 51 in efforts to 'see them aliens'.
The original event was intended as a joke and was titled “Storm Area 51, They Can't Stop Al of Us.”
