Okay good luck if you think that open assembly of persons at the jeep event didn't count as an open assembly of persons. He certainly wasn't over the water by any stretch of the imagination.
As a tipical FAR regulation....it is always open for interpretation....I see your point, Believe me.....But I see mine as the one applicable here which is a good source of debate (again) on what we as Certified and experienced pilots see different....
Regardless of our argument which is amazing we are attacking each other since we are all in agreemnt the guy is in clear violation of 91.119....I will not only suspend his licence but will question his CFII who trained him or gave him his last BFR.....I know one thing for sure....His insurance will probably have a say.....
One last thing.....Most of us aerobatic pilots, we have a minimun floor of 1,500 depending in which class you compete I am limited by myself to 1,500 agl as my absolutelly bottom floor.
Here is the reg...
Sec. 91.119 - Minimum safe altitudes: General.
Except when necessary for takeoff or landing, no person may operate an aircraft below the following altitudes:
(a) Anywhere. An altitude allowing, if a power unit fails, an emergency landing without undue hazard to persons or property on the surface.
(b) Over congested areas. Over any congested area of a city, town, or settlement, or over any open air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft.
(c) Over other than congested areas. An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.

Helicopters may be operated at less than the minimums prescribed in paragraph (b) or (c) of this section if the operation is conducted without hazard to persons or property on the surface.
