There's a great travel TV show called The Seasoned Traveler, for older travelers.  The show airs in Los Angeles on PBS, but not the main PBS station, a smaller station.  We especially loved their recent episode going to Peru, including Cusco and Machu Picchu, and this helped inspire our editor's recent trip there.  Here's the show's website: theseasonedtraveler.com.

 Of course the show covers many destinations you've seen on other shows but the host is knowledgable and enjoyable to watch and its interesting to see his take on things.

Check your local listings for the show in your area, or check the show's website to see if it airs in your area.  The website also has a lot of previews of episodes of the show.
