I think it’s Smilax or green-briar. It is a thorny vine and it grows all over the place on Cape Cod. It is so fascinating to look at and painful to handle. The crazy happy vines seem to be tormenting the angry thorns. You can simultaneously use this stuff to make weapons and decorative arrangements. I try and follow the crazy happy vines with my eyes. For some reason I want to make sense of what they are doing and where they are going.
