This drink may be cold, but the bourbon will warm you right up.
In a big bowl, mix the orange juice concentrate, lemonade concentrate, pineapple juice, sugar, tea, and whiskey together. Pour that stuff into a few shallow bowls, and leave them in the freezer overnight.
Take the frozen mixes out of the freezer and let them stand for around 10 minutes. Use a whisk or potato masher to get the mixes all slushy. With a spoon, scoop out chunks of the frozen mix and drop them into glasses. Top each glass with lemon-lime soda.
