We travelled to Innuvik via the Dempster HWY two years ago and the prices along the way were pretty expensive. Everything is transported in and the gas (except for the subsidized rates offered only to the Indians) was really high. We did a lot of meal splitting and snack sharing. In Innuvik, we could not find local fish even though were were close to the ocean and rivers.
I guess that I have been reading a LOT of Alaskan blogs.
Most Alaskan produce a lot of their own food. They spend much of the year putting away a lot of fish, moose, dear, and the like. In the southern portion of the state, despite the short growing season, gardens are fairly popular and very productive.
For example, from Kotzebue:http://finnskimo.blogspot.com/2012/03/h ... ngues.html
What is also interesting is the price inconsistencies throughout the state. Check out the various flyers at:http://acvaluecenter.com/flyers/large_fz1_21.pdf
