Do any of yall have problems with thistle in your pasture? Thistle has invaded my back pasture this past month and I am wondering how to get rid of it. Daddy said to just dig it up and haul it off (only 10 or 15 plants).

The difference is that the picloram in the Grazon will have residual soil activity that will kill any that germinate around the mature plant that you spray, until that picloram moves on out of the soil. Not good to kill one thistle and have two germinate right beside it.
Whatever you use, do like others have suggested and get rid of the seed heads. A thistle has a lot of energy in the stalk and will continue to mature a seed head long after you cut it or dig it.
At any rate, plan on doing it for two or three years to get complete control.

Only problem is that picloram is a restricted use herbicide and you have to have a license to get it and supposedly legally apply it. But it isn't all that hard to get a license.
