Listen to a segment I did on NPR's Talk of the Nation yesterday with Neil Conan. This summer: Car rental prices are down; the Euro is down; hotel rates are down. The only thing that's up significantly is airfare. Listeners called in with their suggestions about spots in their own backyard we should all visit. My favorite tip: splurge on your next road trip by renting a convertible. Helps spice up the potentially average drive.
