With Ireland it's obvious, with Iceland less so, but still happening.

What I'm not sure on is Greenland. They are remote, few and scattered. Roads are a luxury up there. Work is underway on building the first modern airport, but that only covers part of the western half of a very large country.

The comparison is this - Iceland skirts the line between the civilized world and the wild frontier. Southwestern Greenland is the first stop after you've crossed into the wild frontier, with other parts of the country being even more remote.
