I thought they said 18 miles from Kavik by Super Cub.
Note the over-size tires on that Super Cub! Used to be more or less standard for the bush planes that I used to know when I lived there.
Kinda nice to see a Super Cub on regular bush duty this many years later!
IIRC, the Cub and Super Cub can haul more than they weigh.
