Way too many idiots flying GA, guys who haven't been to a towered airport in 20 years, never make a radio call, and takeoff/land against the prevailing traffic flow. Still wondering if they're oblivious or just don't care. My favorite was a P-51 aviator who never made a call and flew a wingspan under my student and me.

The closer I got to accruing my time instructing, the more paranoid I became, like a cop one day away from retirement...
