Who can not see this large lovely fountain while driving? Of course it shouldn't be moved ! I can't imagine many over the years have run into it!! what, a drunk here and texter there? That's their problem. Move their car to another area, perhaps the junk yard.

The only idea To "protect the fountain" that makes sense is not ugly signs or metal rails. Perhaps attractive lights aimed at the fountain to enhance it and help these visually impaired people see it.
