Im talking basic highschool sports events. I see what you mean, but everything differs from area to area. Where Im an explorer a rig will take a max of 7 minutes to get to anyone within its coverage zone, depending, of course, on weather, time, etc. The second rig, if it is a major event, can come right after the primary rig, or may take a little longer, because where I explore its volunteer, so some people may have to come from home. All Im saying is why waste resources for something with a remote chance of happening, of course a plan could be drawn up if something major did happen, and resources could be brought in quickly and easily. But you really need to base your coverage on what you think your going to need, which differs from highschool, to college, to pro.
