Right or wrong?

i just returned from a trip to Santa Cruz, California. It is a beach town and what you might call hippie-dippie. It is also a surfing mecca. On one of our beach walks, I discovered this wall…

It is my understanding that it has been controversial, as this wall is technically on private property. The part you see is adjacent to a public RV park. The house on this property is on a hill above this wall. The majority of the markings are memorials.

My question is this…do you think it is right or wrong that people use this wall for this purpose? Would you protest if it were your wall? Obviously, the posts are not being removed. 

I understand the law…the rules…I just wonder what I would feel like. I think I would want people to have this place, as long as the area is kept clean and the posts are respectful.

It made me stop and think, so I thought I would put it out there for opinions.
