Edinburgh Winter Sports

I'm working at home, but feeling a bit of cabin fever in the afternoon, I walk down to Braidburn Valley Park to think about a problem. Full winter sports are in action. Kids using sledges, kids using sledges as snowboards, adults sledging with small kids and as snowboards, and adults building wee jumps, so that kids using sledges as snowboards can jump. I can't see that ending well.

Well I have a solution for my problem as well, so I walk home to email the reply.
