Well, I failed miserably, think they were all inside due to the weather, and didn't fancy the rain dripping off their baseball caps onto the trainers.
Although, 'I-spyed' :_
1) Trackie bottoms and clean trainers .... 1 point
2) Trackie bottoms and dirty trainers .... 2 points
3) Trackie bottoms and felt-like zip up garment over baseball cap (is this a hoody?) ... 3 points
4) Trackie bottoms, dirty trainers, and red baseball cap .. 4 points.
Have yet to get the ultimate of 10 as described by Garinda in above post.
Will persevere...
