As a previous renter in that area, I can agree that there are many spots for people to park their vans, trucks or cars.  It was never a problem however as they just needed somewhere to park.  There is a restriction of 72 hrs as you've stated.  

There is a serious problems w/homelessness and I have to state, for the record, that never once did I witness, see or smell (that's legal now) drugs.  I think you've a mindset that anyone who parks in a safe place for 3 days anywhere near YOUR properties are problems.  

Maybe you should sell your two properties and buy in your own state?  They've been doing it for years and I hope they continue to.  There are lots of trees in that area and it is safe for them.  Isn't that more important than your condemnation?  Whitaker is a special area to many of us old timers.   l2g
