Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Q: Is there any day of the week and time when airfares are statistically the cheapest to buy?
I read this question, but does anyone know it specifically for Qantas?

Particularly, I'm searching for a flight from Sao Paulo (Brazil) to Auckland (New Zealand).

Q: I'm vacationing to the Boston area for a week and am interested in Native American history and culture. There's plenty of historic colonial landmarks and museums, but I can't seem to find the equivalent for tribes. (Where) do they exist?

I'm not looking for a specific tribe. I'll have a car, so anywhere from Connecticut to Maine would be possible.

From what I know about history, New England was settled before reservations were set up, and most natives died of disease or were assimilated into European culture. This leads me to believe that tribes don't have much presence, anymore.

Addendum: I'm from California, so I'm familiar with Indian casinos, but a quick search of Indian museums in California shows some around all the major metro areas. I can also find websites of tribes in California that advertise public cultural events. I expected to find similar things in New England. My motivation for asking is primarily for professional development: the content standards for 5th grade social studies includes pre-colonial American history, and this may be my only opportunity to visit this area.
