I would be interested in maybe booking a hunt somewhere for them one day. I believe an acquaintance of mine goes to Maine every year and gives it a shot. I don't think he's gotten one though. I imagine it's the type of thing you need more than a day. Give it like a solid week of combing the woods with a good guide. Not something you can expect to put a day in and be successful.
So I will say, if you like the NS sinkbox thing, you may want to make your way to NJ coastal. There is a ton, and I do mean a ton, of old school heritage hunters here. Up until a couple years ago, I hunted out of a 70's era Barnegat Bay sneakbox. But, with kids coming along for me, I didn't find it smart to be hunting an 11' boat 6' off the water in winter. Now I hunt a more modern rig. Couple guys I know hunt restored glass over cedar and even, all cedar boxes. Some of these guys are hunting over hand carved cedar or cork decoy rigs.
I have a buddy, although frowned upon, who still tows out "floating blinds" that are 6" off the water. They are in reality, sink boxes. You can call them whatever you like, they're still a sink box. He hunts with a famous Nascar driver.
To your point, most of my hunting is the old school way. We hand grass our rigs with salt hay. I hunt over a small black duck rig. Sometimes I'll throw some pintails out. I have a broadbill rig I'll set on the points.
I think if you wanted to shoot a banded bluck duck or brant, NJ is your best bet.
The south shore of LINY has a ton of heritage too but is less accessible with more quirky gun laws.
