Nicholas Crane negotiates wild landscapes using early maps. 2/8. John Ogilby 's "Britannia" (1675). Can Nick use the first ever road map - a 329-year-old document - to lead him over the notorious Trans-Pennine Pass? With the help of experts he tries the journey on his mountain bike in midwinter, having a go at dimensuration (road surveying), and finding old roads might fade away, but never disappear.
