Hurricanes by the Gallon recipe

Pour the Rums, Gin and Amaretto into a 1 gallon Iced Tea Jar with a spigot. Add the frozen juices and the correct amount of water as directed on the can (I believe it's 3 cans of water per can of juice concentrate). Mix well and then add the Grenadine the amount you add depends on your taste, a cup I think is too much I prefer about 3/4 a cup so it's a salmon color I don't like it too pink. Serve over ice....watch out because they do hit you like a "Hurricane".
