Poor decisions usually surface for me, when I’m too tired, too rushed or too hungry.

I found when I first went solo that despite knowing better I was allowing myself to get dehydrated and didn't take the time to replenish my (energy/food/snacks) as we ALL should.

There is a simple chart over the urinal in the men's bathroom at the park office in Atikokan.
Unless you're taking medications that can change your urine color, the rule of thumb is to drink enough fluid so you pee as clear as possible.

Dehydration/ not eating properly will cause MENTAL confusion that you might not even be aware of until you make a stupid decision or find yourself "lost" even though your map route is laid out right before you.

I wouldn't worry about how exactly much you drink because everyone handles heat/exertion differently. The "color" test will make you drink the right amount to get the right result.
