Giant Hogweed has expanded it's territory. This is a large and unique looking plant with caustic sap. The plant is on the DO NOT TOUCH! list as it can cause what amounts to second or third degree burns to the skin within 24 hours of contact, contact with the eyes can result in temporary or permanent blindness. It's range in the US has mostly been the mid- atlantic states plus Washington DC, and lower new england. In Canada it was thought to mostly be confined to south central Ontario. In addition there were scattered reports of the junk in Oregon, Washington state, and BC. Here is the updated range map from the USDA:
