On Sunday of our visit to London, we spent the day away from the city, on a trip to Stonehenge and the town of Bath. I think Stonehenge was my favorite part of the trip. It's hard to imagine people building this structure with primitive hand tools, and the stone had to travel quite a few miles to get to the site. Astonishing.
Our guide, Debbie, told us that there's also a Woodhenge--but it hasn't held up as well.
