This is good. The limes add a nice flavor to the lemonade and the raspberries make it pretty. And you don't have to let it sit overnight. There is a nice flavor without doing that.
In a 2-quart pitcher combine lemon juice, lime juice, sugar, and water. Stir to dissolve sugar. Add raspberries; cover and chill overnight. Serve over ice. Garnish with lemon and lime slices.
