When deciding to hike in Arizona, do what I did:
-Wait until it is 80 degrees.
-No sunscreen.
-No water.
-Don't look at the sign at the beginning of the four trails, and inadvertantly start out on the advanced section.
As the lungs were screaming for oxygen, I took this photo. This is also tghe place where a veteran hiker said "You are half way there."
That was it for me.
