There's one place out back about 20' X 8' that was just a carpet of poison ivy. It's right beside a tree that I need to take down. That patch is what made me decide to start fighting it every place I see it. It was over grown with light brush when I bought the place. I started mowing it and had it cleared out pretty good. But then it covered over with poison ivy.

I just went scorched earth on it. I think it's going to be a dirt patch for a year or so.
