at least wear i was in SD this fall if the indian trust lands were deeded & not tribal owned supposedly you can obtain permission to hunt then lands with out tribal license??? its different on each reservation but wear i was you could not hunt the res lands inside the res boundaries but the lands outside the boundaries that were not tribal owned but labeled as indain trust lands u could hunt with permission but very gray area & confusing for a newbie to the state i did talk to a local game warden he said the same thing but he was the guy that let the cat out the bag & told me the real deal... you still would have to contact a tribal member or even the board to gain access to trust lands so better off to work public much more fun anyway... beautiful country in that area write on the edge of the prairie & the buttes & ponderosa pine forests...
