For those of you who aren't aware, every Saturday morning at 9 A.M., NPR (National Public Radio) 91.5 FM sponsors a show "Car Talk." The hosts are knowledgeable and hilarious. I tune in just about every Saturday and pick up some good tips for my car (a.k.a. Marley). Just when I think I know it all (because of my engineering background), there's always something new to be learned just as there's always a solution for every problem.
