Sources are hard to find. My rule is discreet more than anything else, and the only people I sell to are friends I've known since before I started growing, and ONE other person who's always good to dump my surplus on. But I'm his landlord so he'd better be a good dude about it!
You're going to find a tough time looking for a hookup on the boards since it's against the rules here; all I can suggest is that you hit up college parties at UMass, where dank is in good supply, or make the trek to the ski areas in southern VT. It may take a while, but the Vermont homegrown is top quality.
Funny story, there's a dunkin donuts location that used to have a thing going where you'd just drive up and order a cup of new england clam chowder... lol, but that was short lived. Don't know if they got busted or the guy just got fired, but it WAS funny!
