Emily, I walked up that street two years ago, and it was a workout.
We stayed at a hotel right above the marketplace, about 1/4 way up one of those hilly streets. We had just finished riding in the San Juans and we did not put our bikes back together while in Seattle, because it looked too imtimidating with the steep hills. I mean, I'm a good climber, but those were insane and add in the city traffic=no! If I had known about the paths, we might have done some riding. I mean, I knew about them, but not enough to contemplate a trip on them. Probably a mistake.
