Choosing an Indian Reservation

Im a male nurse that recently graduated with my BSN in Aug. 2010. I have been working in the 'At Home Hospice' field ever since. I am now interested in pursuing nursing within the reservation ihs.gov programs. I have heard your experience greatly depends on the reservation your at. My first three choices based on blogs, location, suggestions, etc are WhiteMountain Rez in ShowLow AZ, Pine Ridge Reservation in SD, and Pyramid Lake Rez in NV. Does anyone have any advice concerning these reservations and which one would be best to pursue??? Thanks
