Well, I think my magic 8-ball was a little ambitious today. 
I did 20... we'll see how I feel tomorrow.
Maybe I was a little dehydrated before I started out (very possible), maybe I just need to route in a water stop even with my new 3-liter pack (also very possible). I ran out of water with about 3.5 to go, so not catastrophic, but I sure could have used a bit more.
Yes, if I had been having any symptoms or if I'd run out farther from home, I would have stopped at someone's house and asked (or stolen water from their hose if no one was home).
