My advice is this, do your best to see and be seen. Turn your lights
on even on good vis days. Give concise and regular position reports
when you are in non controlled airspace. If you are going to have a
mid air then its one of those unlikely times where you were looking in
the wrong place at the wrong time. I've only been flying about 60
hours and the one near miss I had was when there were only two aircraft
(NORDO aircraft notwithstanding) airborne in 30 square miles. We heard
the other guy broadcast his intentions and knew he was nearby but quick
thinking by my instructor averted disaster. We missed each other by a
fair margin but ATC still radioed us for a position report as they got
a radar alert.
