As a bungalow dweller, I can tell you that the Prof has it pretty much down pat (and the cynics are most likley city folks, so I really can’t expect them to see the beauty of 10 weeks away from the crowds, but that’s another story)
The bigger issue we run into is the trading of kulos that each family has gotten over the year. So when I come back after the week in the city and get told, “XYZ’s rov said,… or ABC (who is frummer than us in certain ways) buys this product / eats at this place, even though it does not a does have a hechscher we know / accept…
You get the idea. To make matters worse, the kulos discussed more often than not tread on ground that really should not be fodder for an open forum. But that’s bungalow life mid week.
So back to the opening post, I’m still sticking with my first volley; the minghag hamokom is decided by the place / group you want to identify / align with.
