It is S.A.T.U.R.D.A.Y!   And with fresh mint growing as fast as the garden weeds, I am just hunting daily for ways to use it.  This is one of my favorites.  Cheers!

3/4 cup loosely packed mint leaves
1 cup fresh lime juice (6 limes)
2/3 cup simple syrup
1 1/2 cup rum
3 cups club soda
Crushed Ice

Muddle mint in bottom of pitcher.
Pour in lime juice, simple syrup, and rum.
Stir well.
Fill glasses with crushed ice.
Pour rum mixture filling glasses 2/3 full.
Top with club soda and stir.

Makes 6 to 8 servings, depending on how much club soda you use!
