Around one hundred kilometres to the north-west of Prague, there's a little town called Dubi. Dubi's known for two things - it's home to the Czech Republic's famous blue and white onion-pattern porcelain, known as "cibulak", and it's also famous, or rather infamous, for the E55, the "Highway of Love" - a stretch of road leading up to the German border that boasts one of the highest concentrations of prostitutes in Europe. But a few weeks ago, Dubi made the news for a completely different reason.
