Try not to Crash Into the Tunnel

For unimportant reasons, I opened up Google Maps to a satellite image of O’Hare International Airport, and I couldn’t help but notice a mysterious tunnel in the middle of the tarmac.

At first glance this looks easily big enough to admit a large commercial airliner. What the heck is it, though? The Google doesn’t seem to have an easy answer for me.

Thou Shalt Not Close

The Boston Globe reported yesterday on what city services would be closed in observing New Year’s Day.

Retail stores: Open at owner’s discretion.

Liquor stores: Open at owner’s discretion.

Supermarkets: Open.

Convenience stores: Open at owner’s discretion.”

This implies supermarkets are absolutely open, regardless of their owners’ preferences. This, in turn, implies there’s a law mandating this, since only a law can keep a business owner from closing his doors pretty much any day he wants.

So what’s the law, then?
