I guess the bright side is that I found out about this now, instead of in a growing season or three.
So this weekend we are going to dig out that section and dump it onto our big green tarp. I will wrap it up like a dumpling and leave it in the sun to cook while I figure out the safe way to burn it to ash.
I think I need a half of a 55 gallon drum. They make nifty backyard firepits anyhow. I can have dad weld some legs on it for me, or even better, teach *me* how to weld some legs on it. For that matter, dad may have a drum in the barn.
I can eradicate this thing before it gets away from me - right?
