Took me a bit to realise what was on his camera then I realised it was a similar shot to Sean's.......if I hadn't seen his I wouldn't have guessed, works well in b/w...I bet he didn't know you had taken it!
@happypat It wasn't his but he would have been stood just where the guy was. My kids were off and wanting to explore, no time to wait for my turn to be stood in that spot!
