Get about 30 lbs of ice and put into a large cooler. Put 4 liters of the Fierce Lime Gatorade into the bottom of the cooler. Add the Parrot Bay and Vodka and then add the rest of the Gatorade. Slice up the six oranges, squeeze 'em into the punch and then drop the slice in. This is a guaranteed hit...I had this at a party and all of it was gone (that's almost 11 liters) in under 2 hours.
