Boston Iced Tea

A wonderfully tart recipe for cranberry iced tea. The name comes from the cranberry bogs in the Boston area (so I've been told). Regardless, it's a very refreshing drink for a summer's day.
4 quarts water
1 cup sugar
15 tea bags
12 oz frozen cranberry juice concentrate
Heat water to boiling, and add sugar. Stir until the sugar dissolves. Add tea bags, remove from heat and let steep for 4 to 5 minutes. Remove tea bags, and add cranberry juice concentrate.
Stir until melted and mixed, then allow to cool to room temperate before refrigerating. Serve over ice.
