WHERE THE BUFFALO ROAM
Once considered "lords of the prairie," buffalo are one of this country's most noble, legendary animals. At American Buffalo: Spirit of a Nation, you'll learn about how these great mammals were almost wiped out by greedy hunters a century ago. Roam across the Web to www.pbs.org/wnet/nature/buffalo/ and get the lowdown on these beautiful animals. The Spirit of a Nation journey will also take you to South Dakota's Black Hills, where you'll learn about the efforts of Native Americans to restore the bison to millions of acres of tribal lands.
