SMOKE GOT BAD AT HOME ONCE AND SOMEONE CALLED IT IN THINKING THERE WAS ANOTHER!
I ALWAYS WAIT TO HEAR THE FIRE SPOTTER PLANE WHICH IS UNMISTAKABLE TO AN AIRFORCE GUY!
THEN IF THEY ARE CLOSE ENOUGH.. THE SCANNER COMES OUT .. AND ABOUT TIME I AM LISTENING TO FIRE AIR... THE CALLS COME FOR TRUCKS WHICH IF YOU LISTEN CAREFULLY YOU WILL HEAR THE FIRE / STREET LOCATION WHICH IS HANDY IN DECIDING WHETHER OR NOT TO START LOADING SO YOU ARE NOT CAUGHT BY SURPRISE AND ALSO TO KNOW WHICH WAY TO EXIT CAUSE IN MY CASE IT IS ONLY 1 OF 2 CLOSE BY AND 4 IF FIRE IS FURTHER AWAY.
