The city is currently negotiating with Clear Channel for an advertising deal at transit shelters in the city. As part of the deal, the city wants Clear Channel to set up a similar program. While the such programs are generally a great idea and are particularly popular in Europe, San Francisco's geography seems ill-suited. The city has a lot of elevation changes that might limit the appeal for many people. Nonetheless, it's good to see a city in the US try something new.
