A computer game challenge was one of the highlights of Prince Charles's visit today.
The Upper Teesdale Agricultural Support Services has just received a £50,000 grant from The Prince's Fund.
In the Youth Area of the centre, ten year old Luke talked the Prince through the computer game, and then gave a skilful demonstration.
The Prince's arrival at Middleton-in-Teesdale was delayed by heavy fog, but his third visit in just ten years soon brought the town to a standstill.
Hundreds of people lined the road, including pupils from Forest of Teesdale Primary School, which has just 13 pupils.
Today's trip was organised as part of the Prince's campaign to back rural businesses.
He visited the local butcher's and ironmonger's shops as well as the Farmer's Auction Mart, where he opened a canteen and meeting room.
