Munis for Dummies

I have to say that the "Books for Dummies" are really useful for understanding various topics that one doesn't know much about. I use them often, such as this one on how to garden. I am now reading Bond Investing For Dummies to learn how to buy municipal bonds. I figure that if taxes increase, I'll need to find some way to shelter savings that makes sense. Since muni interest is often tax free, it seems that they might be a better investment than simply putting money in CDs. Anyone have experience with municipal bonds--good or bad--that they can share? If so, let me know in the comments because I would love to hear from people who actually have experience with them as opposed to only reading about them in a book or listening to Suze Orman discuss them on her show.
