I walk to work from Crown Hill to downtown 3 times a week, a distance of 6.5 to 7 miles, depending on the route. As a dedicated hiker, I can put up 30+ mile days routinely, it's what I love to do.
In 2006, I noticed a lot of campers and vans parked in the industrial strip off Ballard, the "Free-Lard" region near 8th and south of Market. Ballard noticed this, and kicked them out. Now I see a cluster of them on Phinney Ridge:This is near the north entrance of the zoo, along Phinney Ave.
These vehicles are all inhabited, and clustered close together. Of course, there is plenty of broken glass in the parking areas nearby. I'm not saying that these people are breaking into cars, but I wouldn't put it past them.
