4 foot tall weeds, and not just any weeds, weeds covered in balls of stickers that look the the ball on a mace.
Last summer I did something to reduce the tedious task of getting all of them off before getting in car.
I "borrowed" a pair of my wife's pantyhose, and pulled them on over my shoes and pants, like waders. When I was done I unrolled them and tossed them in the trash. Not a single sticker.
