Well, casinos are usually built on major highways, and you often have to get a little ways off the main highways to see where people actually live. I've driven through reservations in Minnesota, South Dakota, and Colorado, and what I saw was depressing--the same signs of rural poverty you might see anywhere. But that was years ago, before the casinos. I don't know if things are getting better everywhere, but I know that in some places, they are getting a LOT better due to the casinos. The most profitable ones are those located near big cities, like the Mystic Lake Casino & Hotel in Prior Lake, Minnesota, not far from the Twin Cities, which may be the biggest in the US. There are new housing developments going up near there, which I think are part of the reservation, and quite nice houses, too.

Still, it's hard to see anything you'd recognize as traditional Indian culture, unless you attend a powwow.
