Most cars in our group are using the car colour as the starting point of their radio call-sign
We have found people have a different view whether our car is “red” or “orange” … Ian thinks it is “red” !
So we thought of calling it “Fire” or “Flame‘ …. but there were those in our group worried that this might get confused in an emergency
So “Vulcan” it is
Go google it !
Think Rome not Star Trek
