Query: NOT FOR THE DEADICATED

Definitely not a book for the hardcore--or even casual--Deadhead. Poorly researched, seemingly slapped together, and terribly written, the book gets one star for the photographs which are pretty good (though they're available much larger from dozens of other sources). Full of dreadful misinformation--don't waste your four dollars!
