My favorite is a concoction I invented myself...well, I think I invented it. It may be on a bar menu somewhere, but I haven't seen it yet...
Raspberry Lemonade (preferably the "Simply Lemonade with Raspberry" brand)
Cherry Lemonade Vodka (I've only found this flavor in the Pinnacle lineup)
Triple Sec
I usually free pour, but when I measure it's roughly 6 -10 oz. lemonade (that's *always* free pour), 1.5 - 2 oz. vodka, 1.5 - 2 oz. triple sec. It honestly depends on the size of the glass I'm putting it in, too...but I usually reach for my pint glasses.
