[Q]: Great. Gives you a pause to remember the real meaning of Christmas. Nostalgic and well loved. Without the glitz and flash of so much that modern Christmas has become. Simple and straight forward, young to old can enjoy it.
[A]: Positive


[Q]: Among those involved with the planning and implementation of specialized, multi-casualty incident response, this book is quite useful. Field personnel, command staff, and planners - all will find it helpful. I found it to be concise, packable, and physically handy. About the only thing I'd change would be to laminate the pages for weather resistance.R.D. Lopez, Emergency Medical Services and Disaster Specialist, Dept. of Public Health
