Drinkers are being urged to 'mind the gap' as a new London Underground style map of the town's pubs goes on sale.
The idea is the brainchild of Sheffield based maths teacher, John Coats, who has been producing the novelty maps for eight years and described the idea as a 'Eureka' moment.
"I think pubs are just really important landmarks," added the 36-year-old.
"Most people can navigate around where they live by pubs."
But don't be fooled into thinking he had to put in hours of extensive research and drinking to put the map together.
"It is the internet," admits John, who combines his teaching with his hobby.
"There is a lot of online pub data bases."
The map was created after people expressed an interest through his website and took just a few days work to put together.
It joins more than 40 designs which John has produced ranging from cities as far apart as Liverpool and Munich.
