2020 race takes shape

For two weeks in the summer of 2004, Olympic Park in Athens seemed like the center of the world. Now the park is mostly empty, the buildings and the flies together under the Greek sun.

Authorities in Italy built a new bobsled run for the 2006 Winter Games up in the mountains near Torino. Now that track, which cost $100 million to build, $2 million annually to operate, is due to be torn down.
