I still cant believe that everyone would bring just a sixpack to a BYOB party. And what is he supposed to drink after the first hour?
I personly dont like vodka and other hard stuff. Except a good whiskey now or then or perhaps some captain morgan with vanilla coke. SO i would bring exactly as much beer as i can afford or transport at given time. If there is really nothing but the stuff you bring i wont go with less than 5 litres. Even if thats too much for you its enough to share a bit. I usually took my backpack filled with about 12 bottles 0.5 litres each. That most of the times worked out.
