...or, your Oregon taxes at work.
If the cities I prattle on about interest anybody enough to want a map of it, I'm pleased to let you know that the Oregon Department of Transportation produces street maps of every incorporated city in the State of Oregon, as well as several unincorporated locales.
You can go to the office in Salem, at 13th St NE and Marion, and buy reasonably priced hard copy maps, or go to thier website and download free PDFs of any of them. They also have GIS data for the taking.
They can be pretty large, so if you're on dial-up, there's a wait involved for some of them.
If you take it electronically, it ought to be free: you Oregonians paid for it, after all!

There are also statewide maps and rail maps. Fun stuff, and you can't beat the price.
