Just behind where I live, there is a wide open space in the form of a football ground.
The view from my kitchen window across one end of that same field is one of the reasons why I live where I live just now. (That view was one of the things I immediately loved about this flat when I first came to have a look at it; which will be six years ago in April.)
On rare occasions in the summer, I’ve been able to see a full rainbow (or even a double one!) stretching from one end of that field to the other. There a few things, I think, that give as much impression of “open space” as a full rainbow… (For the camera to do it justice is another matter!)
Water and sky meeting is another of those “openings” that make your mind stretch the usual boundaries. This is from the lake outside town near ‘the House’ (where my parents lived in their retirement years, and my grandparents before them, back in my childhood).
I have to confess though, that while I love looking at water and skies… I really prefer to have my feet on the ground, and civilisation just round the corner.
