Lime Daiquiri

These are delicious and a nice break from margaritas.  Pour the water, rum, and sugar into a pitcher and stir until the sugar dissolves.  Add the limeade concentrate, making sure to stir it in well and break up any frozen pieces.  Pour everything into the slushie machine, turn it on, press the frozen spiked slushie or frozen drink button, and set the temperature to one less than the coldest setting.  Enjoy.
