Worst Bio-Terrorist Attack in U.S. History

In 1984 a group of followers of the Bhagwan Shree Rajneesh faith orchestrated a deliberate attack on the people of The Dalles, Oregon. The faith with roots in India was attempting to keep people from voting in a local election and thereby increasing the chances of their own candidates.
Salmonella culture was sprayed on salad bars in at least 10 restaurants in the area. At least 750 people became sick and 45 were hospitalized. Nobody died from the exposure. The plot was discovered when some of the followers confessed to local authorities.

Three Cups of Tea

After a failed attempt to the highest mountain in Pakistan, American Greg Mortenson was near death and stumbled into the tiny town of Korphe. He was nursed backed to health and promised to return and build a school for the town's children. Fighting, poverty, terrorism and religionous extremism made the task nearly impossible. He built the school and eventually built more than 60 others in Pakistan and Afghanistan. His story is told in the book "Three Cups of Tea".
