Alas, there are no flying sites in Marietta. I live in Eastern Cobb County, and the Marietta location refers to my mailing address. I probably should change the profile.

I hold membership in clubs which operate flying sites in Cobb, Bartow, and Dekalb counties.

Of the three, only Cobb has a noise ordinance and it is prototypical of noise ordinances, replete with terms like annoying, excessive, unnecessary, and so forth. Not one qualitative parameter anywhere other than distances (auto radios are too loud if they can be heard 50' away).

Bartow and Dekalb have no noise ordinances that I have ever found.
