Alley sections often suffer from too wide or too narrow and even too gradated a section. Please share and comment upon good and bad conditions within alleys.
For instance, the Muse lanes in Edinburgh, Scotland are 18' wide with buildings of 2 stories at the sides. They feel wonderful to walk down and pleasant to visit within. Garage heights, however, suggest there is no way a hummer will fit in them. Contrarily the Must lanes in London are often of a much wider section or 30' or larger and provide space to service one's vehicle, or even set-up a furniture manufacturing outfit within them.
