Direct TV, channel 377, provides PBS-YOU, a 24 hour learning channel. Many college level courses are offered including math, science, and english. I found their programming to be great although a lot is packed into each session. Web site is http://www.pbs.org/pbsyou/ I understand that YOU is abbreviation for “Your Own Unuversity.”

North (who although he agrees with some of Bill O'Reilly's thoughts on PBS also has a great deal of respect and supports it. Where would we be with out Klick and Klack on Car Talk. Doesn't one of the brothers have a Ph.D from MIT). North
