A big part of writing is doing the research, but only so much can be gleaned from wikipedia. We have a vast array of experience here and when writing, you need details. Perhaps if we knew what each other did, we could borrow from their experience on a deeper level, ask them questions. I'll start... I was a career firefighter/paramedic. I started in rural firefighting on a ladder company, then moved into industrial firefighting. I became an expert at extrication with the jaws of life, then became a medic in 93. I ran a lot of calls in southeast Texas in a fairly large city and also made many calls deep in the boondocks of southeast Texas. So, I have intimate knowledge of these subjects. If I can help anyone fill in some details, let me know. Next?
