Wouldn't you like a refreshing tankard of ale in the summer sun? Of course you would. But first you need to find a pub that is in the sun.
What you need is Pints in the Sun. This very clever map will help you locate nearby bars. It also very handily provides a 3d map of the buildings in the area and shows you where the shade and sunlight will be at every minute of the day.
