Thats true, but in one county I work in we have an "ICTAC" (1 through 5) its a local countywide mutual aid talk group used for large incidents or multifunctional operations like chases, DUI check points, big narcotics stings, large wrecks, fires, etc. No matter what the agency or rank everyone has the ICTACS, that means if a county roads department truck needs to talk to a city police officer its just a twist on a knob. I dont see a lot of this in the large metro counties. It really makes communication smooth.
