 It's July 22nd, and this is your Fox Daily Snapshot. Today is National Hammock Day. If you're a person who loves to lounge outside and enjoy the fresh air, then today is your day. Made from netting or fabric, a hammock is a simple way to relax in Mother Nature. All you need to do is tie up your hammock between two points, usually trees or posts, carefully lie down in a sling, and then fall asleep as the gentle breeze rocks you back and forth.
