To the farmers among us

Over here in Holland, the toughest grass is quackgrass. At least, thats how my uncle from Canada called it when he was here a couple of years ago.
It has an underground interconnecting root system so it comes back quickly, and can stand drought better than anything. On dry soils quackgrass is a problem because it overtakes the more productive grasses during drought or extreme grazing. quackgrass seems to exist in nearly every continent.

Any pics of what your calling quackgrass. I wonder if we have that here and just call it something else.
