Tentacles of death. I hate these things.
AKA Multiflora Rose, a non-native, super invasive species.
Beware when approaching these things. If you get too close, the first thing that happens is they will grab your hat right off your head. When you try to retrieve it, they will grab your face and slice it to bits and throw your hat further into their habitat. Once your hand is on your hat, they then proceed to wrap around your whole body. Do not move fast! The more you struggle, the more trapped you become. Slowly reach for your pruners and carefully cut yourself free. At best, you will need at least one or two blood transfussions and a new set of camos. These things will easily shred a new carhart in seconds flat![:-]
Lets be careful out there. Consider yourself warned!
