I'd pave the world in that case. Or at least my yard. Though I'm betting the target of this law isn't Joe Average homeowner, but James Bankster who owns three foreclosed properties, and isn't maintaining them before they're put on the market.

This being said, I have no desire to own a house with a lawn, ever. (Unless there's a dozen or so acres of "lawn", I can keep horses, and grow my own veggies, that is )
