A classic, Area 51 is up next as one of the most heavily guarded places on Earth. Area 51 as we all know is “where the aliens are at”, a place shrouded in mystery and only a few elite people know its secrets. Besides being the elusive place that it is, it is also an Air Force base, responsible for the training of many troops every year.
It is a 38,000 acre stretch of land located in Southern Nevada which is essentially in the middle of a desert. It is a wonder as to what truly lies within its boundaries, but maybe it is just an Air Force base after all.
