My original post didn't get into the details of what she has already tried, which includes all of what you suggested. She thinks there's some kind of "conspiracy" between the HOA building crew that set up those lights and the public officials that are dragging their feet and not cooperating. -Dan Heim On 3/29/2013 10:30 AM, Stan Gorodenski wrote: > Dan, > Yes, those were my thoughts.
