So if you’re in a national park on the river are you under state or federal law? I ask a young shiny federal officer this question at the winter show and he could not give me a straight answer. In particular I aked about the Nebesna River. His answer in a round about way was "Thats not my area, you should call the Tok office". Federal law says no airboats in the Tetlin nat. preserve, but if I stay on the river until I reach the wrangle preserve am I good?
