Isn't that the truth? I swear that's EXACTLY what they do.. they know when I'm gonna weed, so they put down as deep as roots as possible so that it's rather futile to pull 'em up 'cuz they'll be right back in 2 days at the same height. And these darned thistles drink RoundUp like KoolAid. I swear they think it's MiracleGro or something...
