Story - Footprints in the Snow

I taught students with significant autism. Just when you think you have things figured out they throw you for a loop. In Utah the snow is unavoidable but most kids like playing in the freshly fallen snow. The first snowfall of the year arrived and with it fear. One student refused to go outside. His communication skills were limited and I could not figure out why he did not want to play in the newly fallen snow. After several days we realized that he was terrified of footprints in the snow. Now tell me how in the world I can avoid footprints at a school all winter long? Lets just say we ran fast.
