I've managed a day with 11000 girl guides, from 4 to one >100 year old lady. I was only watching 11 mind. ;).
We went to Wetherby race course with lots on to keep them entertained. I had my sitter and , thank heavens, we sat a lot. I had a kind of normal day, although I was the only Leader wearing a big rimmed beach hat, and felt rather self conscious. But I've always burnt and I've not trialled this uv sensitivity yet. Absolutely shattered now though but feeling like I've accomplished something. Goodness knows how I will feel tomorrow. I know my ankles hurt.
