Cut the peach halves into thin slices. Place the peach slices in the bottom of a 2.5-quart pitcher, and then top with the raspberries.
Pour in the Moscato, soda, peach nectar, and vodka and give the punch a stir.
Fill a wine glass or rocks glass with ice and fill with the punch, being sure to get some of the fruit into the glass as well.
For the lemon-lime soda, add 1 cup to the pitcher with the other liquid ingredients. If there is still room, add more soda. If not, you can float a little soda on top of each glass ounce you pour the punch.
If peaches & raspberries are not in season, you can substitute a package of frozen fruit instead.
If you use a 40 proof vodka (like Alize Peach) use 1 cup. If you go with an 80 proof vodka, reduce to 1/2 cup. You can add more if you like, but taste test first.
