Join OLLI member Gail Parsons and her granddaughter as they share their 100-mile coast-to-coast self-guided walk across northern England alongside Hadrian's Wall, a UNESCO World Heritage Site. In the year AD 122, Hadrian, Emperor of the Roman Empire, had his soldiers build a stone wall to keep out the barbarians to the north (invaders from present-day Scotland). Hear Gail, founder of the OLLI hiking group, describe her adventures along Hadrian’s Wall.
