• Nine-year-old Ryley, who has autism, has always loved taking a bus trip.
• And as a toddler his fondness for public transport helped with his numeracy skills.
• This summer Ryley, from Stourbridge, in the West Midlands, and his grandmother Mandy are raising money for other children with autism.
• They hope to raise £10,000 for their 23-day challenge, involving 60 different bus journeys from John O'Groats to Land's End.
