Living in my RV to experience a new city... Portland, OR

My experience is not Portland-specific, but west coast liberal cities in general tend to be very, very anti people living in Rvs, campers, etc. in public places. I think because they get so many people trying.

What you probably COULD do, though, is find a driveway to rent for $100 a month or so. Or see if your work will let you park in their lot!
