Bat's Breeze and an active Masaya volcano

Bat's Breeze

I know many ways to get fresh and cold. One can take a cold shower, turn on a vent or look for a shadow under big tree. Those are a few standard methods. But now I discovered another way. One has to find the bat cave and wait for the sun. When the bats are flying out, they can get you fresh.
The bats can fly surprisingly closed to the face but I was told that they would not hit the person thanks to their great echolocation. And I can prove it. Despite that I am really tall, they did not hit me!!!!
