We used to do desert camping in central Utah. We’d see tourists frequently, walking down trails, no hats, maybe a small water bottle in their hands. Usually not.
I’m surprised more don’t collapse and die.
I once saw a woman on the main trial on Mount Monadnock in southwestern NH with high heels on and a dress.
Monadnock is the second most often climbed mountain in the world after Mt Fuji in Japan.
once went for a very strenuous/steep and long hike on a hot day in August with my 20 yo son, we carried about 20 bottles of water for the hike, about 10 each - we were about 50 bottles short of what we actually needed....
