Found it!

Ed, I will take care of making the Pisco sour and bringing what it needed.I have some pisco that I will bring and it is my understanding that some people have some pisco on hand? We need about 3oz of pisco per person per glass.
Of course I can bring a couple of "specialty" ones to try straight, since it is almost like a brandy.
What else do I need to bring for meals and such?
Is the list above with needs and people up to date??
