Oliver O’Driscoll having fun on his sled in the snow beneath Rodborough Fort, Stroud, Gloucestershire.

School closures and snow, head for the hills because you can guarantee there will be children sledding but it is fraught with danger. Not being taken out by a sled but photographing children. Hopefully they will be accompanied by an adult, but not always. This guy was really going for it, but before I could do anything I had to ask permission. Luckily he had been provided with a mobile phone, and after showing him my press card he phoned his mother. I spoke to her, explained who I was and gave her numbers of colleagues who could clarify this. She phoned a colleague, who then phoned me to say I was clear to  take this guys photo. The effort was worth it I think.
