You make it sound like some people feel that "it's controlled as long as it isn't burning my property".
IA about what some people consider safe. We have quite a few counties here that allow burning on certain days. These are counties where they don't have resources for picking up all the debris from their property. It's usually the mountain properties. However, there is always someone who thinks it's OK to burn in the dead of summer when everything around them is dry. Some people really deserve the Darwin award.
