Thanks for the congrats!

Definitely go to Stonehenge.

If you don't want to apply for special access, then go on a hot day and sit on the grass a little away from the stones for a while, watching tourist-henge circling the stones widdershins.

One can glimpse the peaceful Stonehenge that way.

I always circle the stones sunwise (clockwise), against the tourist tide, as the EH path tries to take you anti-clockwise.
Makes me feel good anyway...
