All across the state, one public service group works their regular job, then remains on-call. Around 150 of them met in Flatwoods last weekend. On any given day, they may encounter nice people, criminals, the mentally ill, and government officials. Their work is often dirty and dangerous. They must often raise the money to do their jobs - including salary and supplies - stretch it tissue-paper thin, and tend to required government paperwork. They deal with medical issues, often emergencies, diseases and sometimes interstate commerce. What they do is essential to public health in many ways (and often privately funded), but their task is invisible to society or worse, shunned or shrugged off.
