It’s July 1952 in Oconto, Wisconsin. You wake up, stretch, pour some coffee, all while strange sounds filter in from outside. Some witnesses describe sounds like a combination of rubbing on a balloon, and distant rifle fire.

Only it isn’t distant rifles making these sounds - it’s 175 million …. frogs.
