Yeah, I've thought about doing my front yard in something maintenance-free while keeping grass in the back. It would be so much easier in the long run, but it's a pain in the ass up front and it's a bitch to switch back. There's no way to just abandon it completely, even if I kill everything off with Round-Up that becomes an ongoing necessity or it would turn into a weed-infested nightmare. You just can't keep bare dirt bare.
Plant soybeans or corn :^P
We have some areas around here that are nothing but rock. I'd love to have a few acres like that, Clear just enough trees to wedge a small house in, and leave the rest. Just rocks, ferns, and trees. Maybe a tiny spot in the back for a garden.
I'm trying to think of ways to get rid of my grass that doesn't cost a fortune, but I keep coming up blank. I'd like to build stone works, and I can get stones, but I'd have to haul and place them. I laid natural stones down in the back as a crude patio, and it's shocking how far a big ass pile of rocks go(not very).
