There is going to be like 10 people who are actually going to take it seriously and go to Area 51. The meme was quite funny when it first came out though.
I think there will be people who took it serious and will try to storm it or push the boundaries. Then there will be people like me who will watch these idiots get apprehended by the military police.
I'm sure there will be people that will show up to Area 51 mainly just to have a party and get drunk but there will always be that group of people that take the meme seriously.
