Aircraft; Human Factors
While northbound in level flight at 3;500 feet; we were watching opposite direction traffic pass 1 mile off our left wing. As soon as he passed; we looked forward just in time to see a Beechcraft Bonanza BE35 cross over us on a westbound heading; going over our windshield 40 feet above us. We dived to avoid him. He never made any evasive maneuvers; indicating he probably never saw us.
C172 instructor pilot flying northbound reports a NMAC at 3;500 feet NNW of MZB with a westbound BE35. Forty feet of vertical separation is reported as evasive action is taken. The other pilot did not maneuver.
