Do you run back down with the pack too, or just carry rocks up and dump them?

The pack is full the whole time, and certainly noticeable. The stupid part, which I was contrmplating towards the end, is that I was sweating away, getting quite thirst and I'm sure quite dehydrated, and I carrying about 5 pounds of water, and I don't drink any, because I don't want to mess up the math of how much weight I was carrying for the outing. And I can hear it sloshing, sloshing, sloshing.....

Good mental training too?

Drink.

Well, you're losing weight by sweating, so your math is screwed no matter what.

if you drink it you're just carrying it inside of you instead of outside...
