Marco's Comments:
A couple of methods for a blindfold drive, one of which already in the Dexter. Also a couple of "center tear" variations.
Bought in a lot from Lybrary.com with many of the Al Mann booklets. It came unbound as Chris Wasshuber bought the remainders of the Al Mann's books and has been selling them for years. I spiral-bound it myself (with the A4 binder).
