Where am I?

I'll give you a clue: it's not Holland, although you are forgiven for thinking so. Okay, so you're not completely wrong, the Dutch did have a hand in shaping this landscape. It's the Fens north of Cambridge. Once a beautiful labyrinth of meandering waterways, surrounding the island of Ely, now reduced to acres of flat farmland. A lot of it below sealevel. Which gives me hope, because what with global warming, before too long everything will have reverted to its natural order, and I can walk to the beach, instead of having to drive 60 miles.
