I have long had an interest in neolithic and bronze age England, and on my only visit to the UK managed to visit Stonehenge, West Kennet Longbarrow, Avebury and Silbury Hill. I have read a bit about Stonehenge, and know my stonehenge from my woodhenge.
So it was with great delight that I found something new - cardhenge! If you have an interest in neolithic sites plus an odd sense of humour, you may enjoy cardboard STONEHENGE. : )
