Last night I watched a Tony Robinson Walking Through History episode in which he did a 45-mile trek from Avebury to Stonehenge, visiting many of Wiltshire's ancient pagan sites. He also stopped to try out dowsing for Ley Lines and talked to a man who makes crop circles.
I enjoyed it. If you missed it, the programme is probably still available on catch-up. It was shown on More4 at 9pm on Saturday 4 Jan.
