It wasn't that bad!
I got the front yard done and it only took me an hour. The backyard is even worse, but no one can see it, so I'm going to leave it for another day.
I had to mow done a very pretty patch of purple jolly-jump-ups, it was a little heartbreaking. I think if I ever get a house, I'll just cover my lawn in jolly-jump-ups and never mow at all.
