See what will come out of this cave – your worst nightmare! [photos]

The sun sets on a warm summer night in Texas. At the entrance to a deep and dark cave, a few…
bats came out and started swirling up in the air. Then more and more began to appear. This happens every night, all summer long, at Bracken Cave in Texas. When millions of bats come out to hunt insects. The moment is truly awe-inspiring and a reminder how amazing it can be is the nature.
