At any given hour on any given workday, well, it turns out it’s not a workday at all. Not for these hordes roaming free, anyway. By rights our parks and movie theaters and stores should be minor ghost towns between 9 and 5 – chanced upon by the occasional tourist or late-night bartender but otherwise peaceful. Instead, they’re inexplicably packed. I didn’t doubt that the packers had sound explanations. I just wanted to hear them.
