I have a map

I got a street map of Portland so I can start doing my 'walk all of the city' in a more organized way. What I really need is a road atlas so I can make notes and so I can specify locations on photos. Those aren't really made any more so the ones I've seen online are stupidly expensive. I am pretty sure I can find one for 1/10th the price. This will be a good stopgap, though. My current biggest problem with the project is that I don't want to be walking in the sun and heat. This week should be cool, so I should get a lot done. Fall will be a lot better for really making massive progress and doing all day walking.
