pcappy-08, Beggar's lice are a major pain in the arse in eastern Nebraska, not far from Mudd's locale. It's interesting, the regional differences we all have here in the US. Where I hunt, I never encounter briar patches, but hunting SE Iowa I ran into some patches that made Kodiak Island alder thickets look inviting by comparison!
What I normally try to do is where clothing that doesn't pick up the burrs to begin with, or maybe pick them up but not so tightly that they can't be taken off easily. Or wear knee boots (but the bushes grow higher than that), and have even resorted to hip boots on occasion to deal with that (and poison ivy).
These burrs means a lot of fleece and other materials are rendered nearly useless. There are other offenders depending on the area; I particularly hate foxtail and have thrown away cotton/poly garments in the past (nice comfy sweats) after encountering that.
