The follow up to this map [an as yet unfinished but presentable version]:
For the street names outside of the green belt, and other than the main arterials, were inspired by New Zealand, Australian and Canadian Prime Ministers, international cities (in reverse alphabetical order from Nth to Sth) and the streets on the south side of the river (adjoining Enterprise Dr, Mayfield and Barnard Aves) were taken after counties in Ohio (a list picked at random).
This is the first street map I have ever made and all credit goes to the WikiTravel tutorial for Inkscape I found here.
