Well, my wife grew up near the North Sea town of Husum so salt marshes, harbours etc. are familiar to her.
Even though its not such a great distance its still quite an effort & expense to get over to the UK (flight + hire car or own car + ferry & my wife hates ferries). Now that my parents are both gone we no longer have a cheap "base" to stay in the UK. Last UK visit was for a weekend in January 2014 to attend a 100th birthday celebration (of the lady who looked after me when my mother had to go back to her teaching job to help feed the family, may father at that time not getting much as an assistent lecturer at Sheffield University - a lowly grade that no longer exists I understand). Before that we had a week in the Lake District.
