Climbed Rattlesnake Mountain in my bare feet when I was around 13 years old?? That's the mountain (really a high hill) that is two inches from the right near the top below the higher mountains around Reno, Nevada in this picture.

It is the hill with the very small cliff face near the bottom. I was smart enough though to go around the cliff.
