Actually I guess I should have started at -2, not -1! This is my first full day on Orkney, but the workshop does not begin until tomorrow.
After so much driving in the last 2 days I wanted a change, so I went for a walk to the Stenness Standing Stones and the Ring of Brodgar. It was misty and wet first thing, and indeed until about 10:00, but it cleared a lot then and became quite warm and sunny, though the grass was wet, and my shoes and socks got soaked.
A very enjoyable walk, but not very long as I felt quite tired.
