PS, I have looked around Thatcher park on their Hop Trail... Unless I'm blind that trail is misnamed. I also looked around parts of Grafton lakes.. Nothing.
They were in an urban setting by my wife's salon in Latham. They were just growing out of the ground (duh) between a telephone pole and looked like they had Been weed wacked pretty severely. I clipped the only long green bine and pulled some other old bines that had some growth and roots. I'm trying to root both the bine and the bine/stick parts.
I believe Cluster hops are the most commonly discovered "wild" brewer's hops from coast to coast. As up-state NY was once the epicenter of hop farming it wouldn't be surprising to come across random stands. Same thing with Vermont...
