Narrative:

X-country flight in biplane approaching S21 from the north (approximately 3 mi) flew low 100' along river (uninhabited), then climbed to pattern altitude and landed. During pattern entry small aircraft flew overhead (approximately 100'), made 180 degree turn and flew pattern for downwind landing (landed after I did). The service man mentioned that 'the boss caught you flying low out there and was yelling at you over the radio (unicom) to get out of there.' I explained that in uninhabited areas as long as you remain at least 500' from any person, structure, veh or vessel, there is no altitude limit--you may fly as low as you wish. He then said that, 'I could be mistaken, but I don't think you can do that within 5MI of an airport.' the point here is that many people are unfamiliar with the regulation and could cause problems for pilots even though they are operating within the regulations.

Title: BIPLANE PLT FLIES LOW OVER RIVER THEN ENTERS PATTERN. SECOND ACFT ENTERS PATTERN, PASSES CLOSE OVERHEAD, REVERSES COURSE AND MAKES DOWNWIND LNDG.

Narrative: X-COUNTRY FLT IN BIPLANE APCHING S21 FROM THE N (APPROX 3 MI) FLEW LOW 100' ALONG RIVER (UNINHABITED), THEN CLBED TO PATTERN ALT AND LANDED. DURING PATTERN ENTRY SMA FLEW OVERHEAD (APPROX 100'), MADE 180 DEG TURN AND FLEW PATTERN FOR DOWNWIND LNDG (LANDED AFTER I DID). THE SVC MAN MENTIONED THAT 'THE BOSS CAUGHT YOU FLYING LOW OUT THERE AND WAS YELLING AT YOU OVER THE RADIO (UNICOM) TO GET OUT OF THERE.' I EXPLAINED THAT IN UNINHABITED AREAS AS LONG AS YOU REMAIN AT LEAST 500' FROM ANY PERSON, STRUCTURE, VEH OR VESSEL, THERE IS NO ALT LIMIT--YOU MAY FLY AS LOW AS YOU WISH. HE THEN SAID THAT, 'I COULD BE MISTAKEN, BUT I DON'T THINK YOU CAN DO THAT WITHIN 5MI OF AN ARPT.' THE POINT HERE IS THAT MANY PEOPLE ARE UNFAMILIAR WITH THE REG AND COULD CAUSE PROBS FOR PLTS EVEN THOUGH THEY ARE OPERATING WITHIN THE REGS.
