We're lost

These phone and post boxes became a standing joke for weekend! Everyone's sat nav directed them to these 'landmarks' and were advised kindly by their sat navs "they had reached their destination', this was then followed by numerous phone calls to those already on site to inform them they were by the red phone box, could not find the site and needed further directions. I personally ended up driving in complete darkness (except for my headlights), up a mountain onto private land and slightly panicked when my wheels started spinning and the car would not move.
