Iced Tea Punch

2 family-size tea bags
1/2 C sugar
1-6 oz can frozen lemonade concentrate
1-12 oz can pineapple-orange concentrate
1 lemon or orange, sliced (optional)
2 mint sprigs (optional)

Bring eight cups water to boil. Add the tea bags; steep for five minutes. Remove tea bags and discard. Stir in sugar until dissolved. Pour the tea into a gallon plastic jug with a tight lid. Add the concentrates, stir and chill, up to 24 hours in advance. Before the picnic, fill the rest of the jug with ice cubes and add the fruit slices and mint sprigs.  Serve 16.  Can also add one liter of ginger ale if desired.
