Glastonbury Symposium: Held in the unique environs of the fascinating and varied town of Glastonbury, the Symposium has grown and evolved massively since its inauguration in 1990.
They run two simultaneous Crop Circle tours, each visiting two fresh crop formations (the same ones, but in a different order), giving participants good time to look around, talk things through, be quiet and get a feel of the formations. www.glastonburysymposium.co.uk
