This is an area of land behind Benjamin's childhood home in Northamptonshire.
Mr Lewis was an eccentric old man who ran an electrical business.
His yard was piled high with ancient cars, televisions, radios and primitive electrical equipment, which Benjamin and his friends used to spend hours exploring.
Mr Lewis used to recycle everything - and on a Summer day, the roofs of his cars would be covered with tea bags, drying in the sun and ready to be used again!
