To a gallon size pitcher, add frozen limeade concentrate.
Into a measuring cup, drain both of the maraschino cherry jars to collect the cherry juice. Then, remove the stems from one of the jars of cherries and add the cherries to the juice.
Pour the juice and cherries over top of the limeade.
Add in the Sprite to fill the rest of your pitcher.
To serve, pour over a glass of ice, and garnish with a fresh lime slice or wedge, and a maraschino cherry.
