Coconut Lemonade

Sounded good, haven't tried it.  Since I can't stand shredded coconut, I'll probably just leave it out.

6 to 8 mint leaves, plus more for garnish
1/2 cup sugar
1 cup mixed lemon and lime juice
Rum, optional
1/2 gallon water, or to taste
Lemon and lime slices
Sweetened shredded coconut

 Muddle the mint leaves with a pestle in the bottom of a large pitcher. Add sugar, lemon and lime juice, and rum, to taste. Cover with water and refrigerate until cold. When ready to serve pour over ice, slices of lemon and lime, and coconut flakes. Garnish with a sprig of mint.
