Roby, et al,

Flying a buzz saw over peoples' heads and hovering over the neighbor's dog is just plain dangerous. All it takes is one bad accident to get park flying banned in an entire city. Suppose a PF hits someone? Suppose a whirling prop takes someone's ear off or eye out? Can you imagine the hue and cry, not to mention the lawsuits?

If PFs fly their models irresponsibly it's inevitable that an accident involving personal injury and/or property damage will eventually happen. Then the local governments will take action to ban park flying.
