Lime Slush

Mom, does this sound like the slush you normally make?

11 cups water
3 cups sugar
3/4 cup limeade concentrate
2 liters lemon-lime soda, chilled
Lime slices, optional

Directions: In a 4-qt. freezer container, combine the water, sugar and limeade concentrate until sugar is dissolved; cover and freeze. Remove from the freezer several hours before serving. Chop mixture until slushy. Add soda just before serving. Garnish with lime slices if desired.
