I was cleaning out folders on my computer and ran across this image that I really think helps explain the size of Alaska and the isolation of people not living near the road system. The overlay of Alaska shows how big our state is. The other point is that the red lines are the major and rural highways that our state has. Notice how few. The blue lines are the rural and state highways that exist in the states that the map of Alaska overlays. You can see why we fly everywhere outside of the major towns that we have. Literally no road exist. The red line road that goes to the top of the state is deceptive in one way. It is a highway but is not open to the public. It is the supply highway, formally named the Dalton Highway and locally called the Haul Road. It is primarily used by supply trucks to Prudhoe Bay for the oil companies.
Just thought that you might like the info and perspective for a change.
