Imagine how much time it takes to maintain the acre lot that I have.
Almost none. Of course, it looks "terrible" because it's not a nicely mowed lawn. I have a feral yard.
Ha ha! I think that to myself ALL THE TIME ("I can't imagine how many hours a "real" yard must take...").
Some of my neighbors have some very natural-looking xeriscaped yards with rocks, native plants, etc. -- but I bet even those take some time & maintenance.
In the end, my patio looks nice, so I'm happy I invested a few hours. :-)
