It wasn't a back garden, and if you persist that it was, I can only seriously question your judgment.
Most people have back gardens in excess of 50 metres ?
Try to provide a cite for that.
Dont twist my words Stephen. I said MANY people have gardens in excess of 50 metres.
From what you have said previously it seems likely that places where you have lived (cities) would have very limited back gardens. Country folk often have well in excess of 50 metres , as you must know.
At one stage in our lives, we were the poorest members of a wine tasting group of nine couples. Every home, but two, had in excess of 50 metres back garden. One house had a swimming pool and one house a tennis court. A very wealthy neighbour had a small lake (it was so big and completely natural that it could not be called a pool) and a tennis court, and it was all much bigger than the tapas area.
All in a country village.
