Wow. It's not a feature I'd associate with the Netherlands. I would associate it with here, however. I am less than 40 miles from the 'Imperial Sand Dunes' a huge area of huge dunes. The wind has blown hard the last two days, I could go out today and see the changes... It is where Star Wars sand scenes were filmed.

If you want a place that is completely different but also the same, there is an area of white dunes in Eastern Washington that also harbors some of the oldest known trees on earth. A small population survived the last ice age...

What a cool trip for you to share with us. Thank you.
