Oh good grief. Lived in Willapa valley for years and I have NEVER seen such idiots in my life regarding this string. I grew up on a
dairy farm and was taught from a tender age to NEVER even consider throwing this junk on the ground. I am guessing it is mostly that orangish red sorta plastic crap. If it has melded into the ground you may need to resort to what was termed a 'bull prick' on the back of your three point. I guess a more polite term is a 'sub soiler'.
This is going to take a lot of time and may even take years depending on how slovenly your predecessor was. Monte is a pretty nice area out there and I wish you luck getting that junk out of your ground.
