Seriously, there is some really cool information in there! If you are like me, you never pick it up until you have a question, hear a strange noise, or encounter a new difficulty. But you really should spend a few minutes looking at it, you'll be amazed at what you might learn. Sometimes I look through it just as a refresher. But each time I open it, I learn something new or something I had forgotten.
You'll never know what brilliant tidbits of information are lurking in there until you do!
