Two American Indian tribes have joined the fight to stop Cape Wind, the controversial plan to install 130 windmills in Nantucket Sound.

“We consider the unobstructed view of Nantucket Sound as a traditional cultural property for us,” said Bettina Washington, historic preservation officer for the Aquinnah Wampanoag Tribe on Martha’s Vineyard. “That’s where we greet the dead, and where the sun rises. Once the view is destroyed, it will be gone forever.”
