Keep off the grass

The guy up the street obviously paid a lot for the grass he had laid in the nature strip.  It looks as though it’s high quality.  In fact, even the grass he replaced looked pretty good, so why it needed to be replaced was a bit of a mystery to me.   That said, it seems he wants to protect his investment!  To have “keep off” signs is perhaps a little over the top?

Nice grass

But this is the nature strip!
