Natural areas
In the Netherlands things are pretty flat. The only real mountain we have is the Limburg Vaalserberg, and we don’t have cliffs and valleys either, not to mention canyons. In America, of course, it’s a bit different. There the nature is rough and the landscapes are even rougher. From mountains to canyons: there is quite a difference in height. And now and then helicopters fly there. After all, the area is not always easily accessible by car, but from the air you can get to just about anywhere.
