One point on the tribes and their slavery....The Makahs for example used to travel by canoe to Vancouver Island to bring back slaves from other tribes..one of their sacred traditions like gambling....Trouble is that the Stevens treaties of 1855 allowed them to whale and kill seals and fish but they had to agree to stop the practice of slavery. They agreed and so they can't claim the right to have slaves anymore. I can't seem to find the part about fireworks though.
