I was able to go about 50 blocks on Klickitat, a very pretty street.
It's where Ramona Quimby lived!
Klickitat was the safer route suggested at ByCycle.org. The street is painted with these handy symbols.
Next was a beautiful ride along the river on the Eastbank Esplanade...
...then over the Hawthorne Bridge
(See- there I am!)
After a short zigzag through downtown, then it was up the big hill on Terwilliger...
...and I arrived victorious at my destination!
