I wouldn't necessarily call them "secret", they don't hang big posters up announcing the matches that's for certain. I mean that's just asking for the roads to be lined with bunny huggers and bleeding hearts.
The last big public match was the Labor Day Tournament at Hegins, PA. They shot that one on the baseball field for years until the PETA peckerheads finally wore the city officials out and they told them they couldn't have there anymore. The tournament still goes on and still draws a crowd but it's shot on a private club now.
