Your picture reminds me of one of my favorite Yosemite Valley tourist moments.
I can't remember what specific climb/hike we were doing, but I remember an icy winter day in Yosemite Valley. We were walking back to the shuttle bus to get back to our campsite (only time of year I'll camp in the valley - bad winter conditions = no people) and decided to detour and check out Lower Yosemite Falls. This was before they redid the area. We had our crampons on. I know it was a really icy day, I just can't remember what we were doing before this point. It could have been a normal hike, with the crampons to help with the ice. In any case, we had our crampons strapped to our boots.
The whole paved trail to the lower falls was covered in a sheer layer of ice. At that short little steep section right before the falls we ran into a group of people who were walking to the falls from their tour bus. There was a woman there in strappy 4" high heels standing at the bottom of the small slope. She had fallen several times while attempting to walk up the ice in those shoes. After seeing us walking across the ice in our crampons, in broken english she asked if she could buy 'teeth for her shoes' (in the parking lot? I couldn't understand. We said something about the mountaineering shop at curry).
Every time my husband sees me in heels now he asks if I have crampons for them.
