Movement of Goods
The main way that goods are transported would be through the sky or in marine. It is slightly different though, considering Alaska's transportation system is slightly scattered over the whole landscape of Alaska.
Alaska's Major Imports and Exports
Canada and Alaska work very closely together with their goods, out anyway, the major export of Alaska would be seafood and salmon, and lots of crab, mostly seafood. The main import of Alaska could be petroleum, probably from the farms that need energy or all the homes that scattered across Alaska.
