I was very fortunate to travel with my mother (who was born in England), along with my very good life long friend (partner in crime), to Europe from the US when I was finished with high school. Very brave of her to take two teenagers to Europe!
One of my fondest memories was a day trip to Bath, Salisbury Cathedral, and Stonehenge on the Salisbury Plain. At that time, you could walk among the ancient stones and imagine what the stones had witnessed. It was a sunny day, the grass was a beautiful green; we had free reign to wander about and marvel at the megaliths, lintels, and surrounding larger stone circle. Today, the stones are blocked off to preserve the monument, however, one can still see them and take photographs from the protective perimeter.
One of many wonderful memories of that trip...
