I might have mentioned some time in the past just how much I dislike Saw Greenbriar.
After pulling out about ten square feet of that crap today, I like it even less. That shit's like barbed wire, only it's alive and grows all over everything.
The sad part is I have at least 100 square feet more to go. If it weren't underneath power lines, I'd just dig some fire lines and torch the crap.
