On the Rocks: Negroni Punch.

It is supposed to be in the 80's this weekend, here in NYC and I was thinking this might be the perfect weekend drink.
Ingredients:
- 4 cups assorted fresh fruit (such as berries, pitted cherries, and pitted sliced apricots and peaches)
- 2 to 4 tablespoons sugar (optional)
- 1 cup Campari
- 1 cup sweet vermouth
- 1 cup gin
- 2 750-ml bottles chilled Prosecco
- Ice cubes
Place fruit in large punch bowl. Sprinkle with sugar to taste, if desired; stir and let stand 10 minutes for sugar to dissolve and juices to form. Add all remaining ingredients except ice cubes. Divide punch among 8 tall ice-filled glasses and serve.
