Managed to make it there as much of the NE countryside was closed with the national Foot and Mouth Disease outbreak. The horizon was just a series of evenly spaced out smoke-trails from the pyres of burning livestock. 2001 I think. It felt positively futuristic and idealistic compared to the morbid dystopian reality going on outside the grounds. It was rumored at the time that the F&M outbreak was just a ruse to eradicate Mad Cow Disease from the National Herd, and that the MOD had been calling lumber merchants about wood stocks in advance of the outbreak. I don't believe any proof ever emerged. Irish special forces were employed along the border with NI after an outbreak in Country Louth, to snipe wild animals such as deer that could carry the disease across, with their national herd counting for a much more significant proportion of their GDP. We were all walking across disinfectant mats at railways and airports for most of the year.
