A Painted Garden?

A few days ago, I was walking to school to pick up my son when I noticed a lawn that looked...well...odd. I didn't see it at first, but as I got closer I noticed that where the grass met the sidewalk, the cement was also marked green. It seems that someone, for some reason, PAINTED THE LAWN!

Now, this lawn was not in particularly bad shape and with all the rain we had this season, it shouldn't have been turning brown. Still, there it was...painted.

So, I started thinking of reasons why the owners might have decided to take this action. I suppose it could have been a food coloring-based color and perhaps it was part of a re-seeding project. Still, I didn't notice any seeds or water run off. Perhaps it needed to be greened-up for a television or movie shoot. I hadn't seen any production companies in the neighborhood and they are sort of hard to miss, with all their tractor-trailer rigs, lights and people. Maybe they were trying to spruce it up to take pictures for real estate brochures? I didn't see any For Sale signs, though.

I guess I will never know what happened to that lawn unless I run into the owners next time I am there. Until then, it remains yet another LA garden mystery.
