OOH! I've just gone to "google earth" and got an aerial shot or two.....
The end of my back garden is about half an inch beyond the end of that horrible pointy thing in the picture.
The area beyond my back garden - where the pointy thing is - is the playground of the local Junior school (screaming little brats, the lot of 'em).
To the left of the pic is the park, and golf course and woods beyond - where I walk the dog.
The three strange circles at the bottom of the pic, are paddling pools in the park (more screaming brats).
The line that runs between the left "google" and "earth", is the Grand Union Canal.
