"Bug Juice" is the name of our favorite summertime drink, and it brings back such fond childhood memories!
You have to make it in a large drink cooler when you're expecting a crowd because it makes a ton (3+ gallons?).
All you need are two cans frozen lemonade concentrate and one can grape concentrate (all approximately the same size). Follow the directions on the can for how much water to add. (I also added several extra cans of water because it was too sweet to me otherwise.) Enjoy!
