Yep and how bout mma fighter Evan Tanner.
Guy went out in the desert.. and he prepared.
How much water baddog do you bring? See right now I am already a pussy as i would prob need to carry at least 4 gallons.

Way more than needed cause I have to feel safe. Actually that aint that much water, ok.. 3 cell phones.. for backup.
Tanner ran short on what water he took with him on foot and it caught up to him b4 he could get back to base.
So yeah, gotta respect heat.
