Have you noticed.

[flash]

I will trade you sticky weed (thistle) for all those helicopter thingies you are fighting with.I dont know if yall have thistle in the colder climates but you sure dont want any. My property is surrounded by farm pasture land that is covered with thistle and when it blooms it releases thousands of tiny seeds that find their way to my yard. I have dug up several hundred so far this year and they just keep coming up. There is no way to control them without spraying all 80 acres of them ,so I just dig them up between mowing. I hope you never encounter anything as stuborn as this stuff is. And it makes for a nice uneven yard from all the holes from the root balls.
