I am taking a speech class in school and I have to do an informative speech. I love biking so I thought I would do my speech on How to Change a Flat Tire on a Bike. It got OK'd by the teacher, now I just need sources for my biblio. I am allowed to have two internet sources and 3 "other" sources (i.e. magazines, movies, newspapers, etc.). Do any of you know off the top of your head some great sources about how to change a flat tire? I already have a couple that should work, but I figured I would ask. Thank in advance.
