Was "the perfect shot" really worth it?

A woman lost her footing after stepping over a retaining wall to take a photograph and went over a cliff, falling 500 feet to her death in a canyon, Yellowstone National Park officials said.

The 52-year-old woman was visiting the park with her husband and two children.

Her husband flagged down a passing motorist, who called 911 after the Saturday morning accident at an overlook along the Yellowstone River, park officials said.

A ranger rappelled down the canyon wall to reach the woman, but she was dead at the scene.

Condolences to the family of the deceased and all that -- but was there no consideration given to the idea that the wall was there for a reason?
