Taverns shown thus

I'm working in a coffee shop, and I just noticed a cycling map of Portland from 1896 on the wall.

First thing I noticed was an ad for a fabulous olde timey women's cycling sweater. Do want!

Then I noticed that practically everything was marked orange, like it was a great road for cycling (like, say, Foster). So I checked the map key to make sure I was reading it right.

The map key said:
Good roads shown thus. ===
Fair roads shown thus. - -
Rail roads shown thus. ---
Taverns shown thus. []

Portland cycling culture is much older than I thought.
