It sounds like a scene in a horror movie. Imagine you are walking along a trail. As you come around the bend, you see a Cobwebby Thistle (Cirsium occidentale) standing at least 6 feet tall. But you’re not worried - the thistle is at least two feet in from the trail. You approach...the music swells ominously...suddenly...the plant lurches towards you and gouges its spiny thistles deep into your shirt, a hold that will...not...let...go. Shriek!
