Agnes Boisvert, an ICU nurse at St. Luke's hospital in downtown Boise, Idaho, spends every day trying to navigate between two worlds. One is a swirl of beeping monitors, masked emotion and death; the other, she says, seems oblivious to the horrors occurring every hour of every day.

Each family had their reasons for ending up in harm's way.

For the Harts, it was the chance to have a large backyard in a quiet part of Ashland, Ore. The porch of the Baltimore house was perfect for Scott Harris' barbecue equipment. Kevin Boudreaux had grown up on the bayou and wanted to settle near his childhood home in Cameron, La.

Fifty years ago, two astronauts became the first humans to set foot on the moon. Like many explorers, they documented their accomplishment in photographs. The images they took are some of the most enduring of the 20th century, traveling from Life magazine to MTV to Twitter.

An hour south of Charlotte, N.C., two forks in the road beyond suburbia, a freshly constructed house sits in a wind tunnel waiting to be set on fire.

To the left of the house is a brick wall with a hole in the middle, made by a 2-by-4 propelled at 70 miles per hour.

In front of the house is a metal staircase five stories tall. At the top are the hail guns.

More than 100 fans begin to turn, slowly at first and then faster. The ember generators flicker on. The fire is about to begin.
