Daddy had an unexpected day off this week, and so we decided to go to the cinema as a family. But to make a whole day of it he planned an extra element, indulging our new-found love of geocaching. He didn’t tell us what we were looking for, simply plugged in our coordinates, popped the top of the Mini, and drove us to Frithsden Beeches. Handing me the iPhone, pre-programmed with the coordinates, he fell into line behind me and the Bug. Knowing my way around the geocaching appfollow I quickly figured out that we were en route to the actual Whomping Willow used in the Harry Potter films.
