How it works is you can travel in your own motor but have to be at Wooley Edge at the stated time, someone from Leeds has the tickets from his open car boot and exchanges the ticket on production of the voucher.
The fella is surrounded by Police who film you as you exchance your voucher, they also film the registration of your car, you are given a leaflet telling you what carpark to head for, but you are free to make your own way in and maybe squeeze a hours of pub time in if you get there from the start of the pick-up time.
That is why i refuse to be dictated as to how i attend a football match, i'd rather not go.
