This is the drink I made for Whitney's shower.
3 cups water
3/4 teaspoon fresh lime juice
1 (12 fl. oz.) can or bottle lemon-lime flavored carbonated beverage
1 cup crushed ice (Shauna made her famous "ice ring" with lemons frozen in it)
1 cup fresh raspberries, garnish
18 mint leaves, for garnish (optional, but really good!)
