rebshidduch, bungalow colonies are a uniquely NYC phenomenon. Contrary to popular belief, the area outside the Greater New York area is not third world.
Basically, Brooklyn is uninhabitable in the summer, so wives leave their husbands there, take their kids, and go to shacks in the Catskills. The husbands live on takeout food during the week, and fight traffic on the way to their families for Shabbos. Then they fight traffic on the way back to Brooklyn on Sunday.
