My wife just picked up what has to be the most expensive blender of all time at Costco, but I must admit it is unbeatable for making drinks. I've made a Muscle Milk (powdered) post-ride drink with ice and bananas and I thought I'd see if anyone else is using one of these machines (Vitamix) for pre or post-ride nutrition - and if so, what's your favorite drink to make? A friend made one with peanut butter, protein powder, ice and chocolate that was awesome, but probably too high in calories.
