Want tourists? Arthur Frommer says give them free transit

...The effort would take the form of an announcement by the President that henceforth, foreign tourists visiting the U.S. would receive free-of-charge, in-city transportation on the subways and buses of our dozen-or-so most important touristic cities. They, their mayors and city councils, would be asked, as a matter of patriotic service, to create a system whereby hotels would be authorized to issue free transportation cards to overnight foreign guests, upon their presentation of passports identifying them as bona fide tourists.
