Gas prices are up across the country, and so are the numbers of people taking public transit. Host Melissa Block checks in with mass-transit officials, ordinary commuters and experts on how fuel costs are changing -- or not -- the way Americans travel.
Belinda Boyd of Knoxville Area Transit says she hopes some of the people who have started riding the bus because it's too expensive to drive themselves will continue riding even after gas prices go down.
Commuters in the BART system in San Francisco talk about the reasons they take public transit.
Block also talks to Alan Pisarski, author of Commuting in America, who says most people aren't switching from car to public transportation -- but that they are doing other things to conserve gas. And we hear from Daniel McGinn, a national correspondent for Newsweek magazine, about why he likes his long commute in a car, even though it's expensive to fill up the gas tank.
