PWYP = Practice What You Preach
This is an annual survival get together organized by Terrill Hoffman on property he owns in North Carolina. Includes skills courses and such, pretty informal gathering that's grown to a good number of good folks (for the most part <g>) over the years.
There's a PWYP sub-section over on Knife Forums Outdoor Survival Forum:
