In a large pitcher or bowl, add as much ice as you want. (The more ice you add, the more watered down the drink will be as it melts, of course.)
Add the soda and the frozen limeade.
Add all of the sliced cucumbers and lime wedges (or reserve some to garnish individual glasses).
Stir together until the limeade melts.
If you serve it right away, the cucumber flavor will be light. I like to let it sit for an hour or two in the fridge because I like a stronger cucumber flavor. This drink is nice for parties because you can make it ahead and pull it out right when the party starts.
