Nah, mow your lawns people. Nothing worse than having neighbors who don't take care of their lawn and leave it looking like a mess. There are better ways to help the environment that don't involve making your yard look like ass.
Pretty lame? I think it's pretty lame to leave your lawn unattended longer than it needs to be. It's an eyesore and it's just going to attract snakes and shit if you let it get too high. You can have a well attended to lawn and plant flowers and other things to be climate friendly. Leaving your lawn looking like you abandoned it for a month isn't doing a whole lot.
I gotta agree with this. I'll keep working on my garden and still cut my grass. I don't need to be wading through ticks and shit just to get to my car.
