I think most of Portland’s electrical power comes from three dams along the Columbia River, damns which a couple of Indian tribes want shut down to save the Orcas. (Orcas face a dwindling food supply because of competition from seals, who are a protected species and are over-breeding and eating too much food.)
Over here in eastern WA, home of many Columbia and Snake River dams, it isn’t the Indians that give us much “damn” trouble, it is white liberals from Seattle and Olympia.
