Statistics says that if there are 1,000 biggish places in a country and a
small percentage of slightly obsessive mappers available, a random
percentage of whom will meet OSM and get addicted then a percentage of towns
around where they live and go will get mapped fast. However... waiting for
obsessive mappers to turn up in every unmapped location in the country is an
entirely different matter and has a very low probability!
