I started this way back in 2011, as a map of the city of Dallas. I posted it here in 2013 and it took off from there. Well now somebody's gone and deleted the boundary that was clearly labelled "DO NOT DELETE" and added one of Wichita's ATIs. Its open contribution, so feel free to add what you want.
