lemonade, like at the easter show, but probably healthier

do you ever buy those big lemonade drinks they sell at the easter show? you know, the ones which are in a big tank with the lemon rinds floating in them and lots of ice? we do, and we buy the really big one because we like to share it (between the three of us, and no one else). it's always so refreshing and the acidity's just right to cut the greasiness of all the junk we eat when we're at the show. doesn't this sound bad? so much junky food...and drink.... i reason that it comes once a year, and the show's the only place where we get this kinda stuff. i'm sure it's available all year round at markets and the like, but for us, that's the only time we see it.
this lemonade is my imitation of the one at the show, but i'm sure it's better because it's home made, and as such, we would take extra love and care when we make it. like washing the lemons before we use them and not adding any preservatives or anything unnatural.....and since this is so wholesome sounding and all, one of these days, i'm going to post something to "balance" it, like the recipe for corn dogs (yum) and cheese on a stick (yum yum).
we didn't make it to the easter show this year, so i think miss k might be entitled to her annual quota of junky easter show food, albeit my version of it.

1 cup fresh-squeezed lemon juice (about 6 washed lemons, and retain the rinds for the garnish)
7 cups water
1 cup granulated sugar

combine the lemon juice with the water and sugar in an 2 litre jug and stir to disslove the sugar. if you like, you can stir, go away and do something and come back to it and give it another stir, and before you know, it would have dissloved.
place the jug in the fridge until ready to serve.
to serve, fill a large glass with ice and fill the glass with the lemon concoction. to give it the full easter show effect, put half a lemon rind in the glass, as they do. me? i like to slice the rind into slivers before adding it to the drink, so they release lots of lemon flavour.
