It’s pretty bad here too. There’s a big patch of it down the road along a stream that feeds into the Winni River. Last year a patch sprouted up roadside halfway up my hill and I’m tempted to roundup that shit myself before it starts spreading.
I’m downwind of Winni on NE flow so it stabilizes me in these self destructive sunshine days in spring and we stay mostly sunny. You can see it downwind of Sebago too on vis.
