Wow. What a hornet's nest!

So if you don't own a copy of RUS.. should you risk buying one? I don't own one and always figured I ought to if I want to brush up on things before going and trying find some group to hang with in Southern California? I probably won't bother. I started making my own songbook plus some reference Audio Tape mixes of the songs I really like but I got distracted after the workbook exceeded 100 pages. I never did get around to finsihing those audio tapes.
