It has always amused me that about 90% of the work put in on grass in urban areas is strictly for social, rather than personal, benefit. All those front lawns, manicured to within an inch of their lives, and not a soul lounging around on them. They are strictly for show.

My wolf descendents, however, LOVE industrial turf, that thick heavy grass planted around commerical buildings. It's like catnip for their dog feet...makes them grin just to walk on it.
