Hudsons pear! This stuff is very bad indeed, I only took two steps and I had some on my shoe as I got out of the car.
Last year a miner warned me as we walked the field, my thong just touched it and a piece hit me in the back of the leg.
Later as I went over for a closer look at it I poked it with a stick and bugger me it got me again! Sh-t no kidding you can't go near it without injury. It kills a lot of animals as it's barbed and won't come out of the skin.
It's only around the Ridge here as it escaped from a garden, you can get free spray packs to Poisson it. But I feel a all out war should be done as it's going to cross the country sooner or later.
