Video: Silverstone: F1 fans tackle the mud Silverstone officials said they would refund unused tickets for Friday and Saturday and in a sign of mounting desperation asked anyone with public car parking passes to stay away on Saturday, qualifying day for the race, to ensure fields are not too churned up for Sunday's race. On Friday, cars were turned away from private campsites, while at the main official site, camper vans were towed in one at a time. Aerial footage shows the extent of the parking problems, with large sections of the car parks turned into thick mud. An extra mile of filter drainage has been put in this year and 1,100 tonnes of hardcore added to car parks, but the sheer number of people trying to get into campsites without pre-booking, coupled with the weather, has been hard to handle. Camping is a big part of Silverstone, which is surrounded by fields in the heart of England, with many drivers staying in motorhomes on site rather than retreating to luxury hotels.
