NPR (click on the player above to listen) gives the San Francisco Airport Museum a little press which, you’ll find if you listen, is something they don’t consider necessary what with all of the regular foot traffic:
In airports, most folks are in a hurry — or can’t be bothered — or would rather sit at the gate and twit or tweet. But Garfield says that if even 10 percent of the passengers stop and look, that’s more visitors than most museums will ever have.
“This is the busiest terminal in the airport,” Garfield says. “You might see 100,000 people a day passing through here.” The American Association of Museums says the median attendance for U.S. art museums is about 44,000 visitors a year — so consider that SFO serves about 38 million passengers a year. That could add up to quite a large number of art appreciators.
