I myself have only heard second-hand (from my ex-wife) just how bad off folk on the rez - and off - can be, but even that is pretty scary. I don't know that getting a casino would be much help. I understand tribal politics can be as murky as anything out of DC, so what would happen in the long run is anyone's guess - but hey, give them a chance. It'd probably boost the whole economy of the region just from tourist traffic.
