Where'd the Spinach Go?

So I had my first green smoothie today! It is absolutely delicious! I used probably 3-4 cups of spinach, and I can't even taste it over the fruity flavors! It is actually a much deeper purple than what you see in the picture -- sorry I have a crap camera =-]

First Green Smoothie
1/2 cup water
3-4 cups fresh spinach
small handfuls of raspberries, blueberries, strawberries
1 whole banana

Blend water, banana, then each different berry, then spinach.

NEEDS
Drying Rack! We've seen some in the stores around here, but I would really like to try and get it from someone else. Do you have one and not use it? I'd pay a few bucks for it too!
