Last week. My FD was assisting the PD looking for a missing child. Discussing, planning and setting up a grid search with a Garman or Tom Tom was not working. I walked to my command car, came back, and laid out a real life city street map on the hood of the police cruiser and we could all see what we needed to do. Planning became a breeze. Additional: The missing girl was safely found - she went with a friend (on the wrong bus) to the Boys & Girls Club.
