Are you joining John to walk to the Big Session and need to park a car at the Catton Hall site so it’s there when you arrive?
The festival organisers have said that walkers can leave cars in the BS car park on the Wednesday and Thursday. All the setup crew will be there so there will be plenty of other vehicles parked there. However, there will be no overnight security and parking is at your own risk.
The Big Session signage will be up by the Wednesday so when you arrive at Catton Hall just follow the signs and they take you into the car park.
