One of the great thimgs about coming on the UK tour is the sunrise access inside Stonehenge. Even people who are DNA-challenged to rise before the sun (like me) look forward to the soft amber light washing the stones out of darkness. Assuming it stops raining; this is England after all!
I think the draw, for me, is experiencing the site in near silence, before the cars and trucks make their journey to office world. And the willing Infodels who make this pilgrimage have a rare opportunity to hear the sacred space, a rare moment of introspection that will move even the hardest of hearts.
