I'm looking for a hard copy of John Petrucci's Rock Discipline.  Not a pdf file.  

Anyone know where I can get one?

Junior's usually at least a little terse, but he knows his stuff. I've always read his posts in a grouchy grandfather voice, a grouchy grandfather with a huge stiffy for alternate picking.
Besides that, he's right this time. As usual.
