Everyone has tales of how successful it was, or how poor it was.
Personally, if that was how it worked with a 13,000 crowd (no way was there 17000 in attendance), I dread to think what it would have been like in a 30,000 crowd
Remember, anything over about 18,000, are not regular fans, so the system would be new to them, causing even more confusion !
Give me season ticket cards, much simpler
