A friend (stop laughing AWG) I went to school with has organised the annual Tribfest at Sledmete House for years. It’s his only job as he makes enough money from it to see him through the year. It’s a three day event, £82.50 per day, or £165 for all three days. As I say he’s done it for years, and it attracts around 4,000 per year, so the best of luck with attracting 10,000.
