I published my 2009 PCT journal. I didn't get an ISBN number. Perhaps that is why it appears to be cheaper than Piper's Flight. I call it Adventure and Magic because I had so much trail magic. Unless I get an ISBN number, it won't be available through Amazon. I haven't decided if I will do that.
Update: I decided to get the ISBN number. That bumped up the price. Bummer. I doubt anyone will buy it anyway, but maybe somebody will. At least I have a copy for myself. It is nice to have my journal so nicely printed up as a memento.
