    Their wooden construction seems quaint, but wood is the best insulator, and it swells to prohibit leaks when the tanks are filled with water. For the buildings that have them, there's no better way to enhance water pressure or fire safety.
  2. You'll find few better role models.
    They can weather any storm. They stay above the fray. They are humble uet dignified, sturdy yet graceful.
  3. They help you figure out who to avoid.
    Like bodegas and the subway, their gritty appeal eludes people who aren't quite worth your time.
