Temporary Flight Restrictions are not uncommon with things like this. When there is a dozen news copters flying around and a few rednecks in their Cessnas safety becomes an issue.
Or course one can retard it down by claiming it is a "no fly zone over America" because even though one can complain that the government lies to us, ( or act as if they are in the "know") one sees no problem in posting outright lies, or fear propaganda, and allows one to be subject to Alex Jones type rhetoric. (which I have said repeatedly that's it's fit for the lowest intellect). Typical retarded BS.
