Portland OR
1:1 map of Portland OR – does not quite get the whole of the Portland metro geography due to scale (The tip of the north Portland Peninsula is cut off, doesn’t extend only really extends to the beginning of the eastern part of Portland, and doesn’t go much past Ross Island to the south.
I only put in one loop of train tracks and just a bit of I-5 (because Portland is dumb – I think), so feel free to make it as close to realistic as you want, or try to make a different / better city.
