Stonehenge--How were rocks moved??

I found a great YouTube video to share with you about Wally Wallington, who is experimenting with different methods of moving large rocks, such as those found at Stonehenge and Avebury, using only what was available technologically in Neolithic times.  I love his enthusiasm!  I was so happy to see him at work and the support his family was giving him.  I know you'll love this!!
