Both of my close calls have been at non controlled airports. It's suppose to be pilot controlled, but most of the near misses are due to Captain Oblivious. I had a near miss on landing with a twin that was landing down wind. When I finally got on the ground, I walked into the FBO to find Captain Oblivious on the phone with the owner trying to blame everyone and everything but himself for running it off of the runway through the drainage ditch and into the barbed wire fence at the South End of the runway. My other was with a Glider Pilot that was flying, I'm talking on the Unicom Frequency no one responds, my Zaon PCAS shows an aircraft nearby. I'm looking and finely see the knife edge if the glider wing as he's banking. He was above and in front of me maybe 500 feet.
