These signs just went up near a small shopping mall in Portland. Might as well be done with it and say, "No homeless people sleeping in their cars or recreational vehicles allowed."
There have been recreational vehicles parked on the street right in back of the large supermarket from time to time as well as cars left there. One assumes they belong to people who are homeless and living out of their car or recreational vehicle.
I'm not sure how much good this will do. Just shove them into the neighborhoods near there where it would be hard to put up the no parking 10 pm to 5 am signs because home owners and renters use street parking for their vehicles. Though most people with recreational vehicles park them on their own property.
Not an easy solution for this.
I'm kind of in the middle. A young friend of mine sleeps in his car and has for about five years. He doesn't do drugs and is clean and neat. Just isn't in to having to work full time to pay rent. Actually, he does outdoor preaching and wants to be free to do that. He supports himself by a private business of doing fencing, digging, sprinkler fixing and other such jobs, and could easily go full time but wants to spend his time in ministry. So he just does what he needs to pay gas, food, clothing, car insurance, cell phone and those kinds of things.
Other neighbors I know have encountered homeless people going through their trash and recycle bins and leaving a mess--not to mention drug needles and paraphernalia left near homeless camps.
It's not an easy problem, and these signs are another one of the City of Portland's clueless responses.
