Here in Vietnam we have an interesting address system. Between main streets there are dense networks of very narrow streets, impassable to anything other than pedestrians. These are called hems and none of them have names. These hems are kind of fractal in nature. From a Main Street will branch a thick hem. From that will branch ten or more medium hems. From each of those will branch ten or more thin hems. House addressees are relative to the ‘root’ Main Street house number. Hence Phan Long 56/4/9/12. Locating these houses is always an adventure. It does not help that many of the hems are dead ends, but few are marked as such. Neither does it help that even Google maps gives up in the hems heartlands. It’s a real case of ‘you can’t get there from here’.
