Slip Sliding Away

This could be the last post for a while. Whilst walking to our local drinking hole, I took a shocking fall and managed to take all of my weight (which is a fair amount) on my left elbow. Things are fine at the moment, but I fear that tomorrow morning the left arm could be out of action.

I would like to ask a quick question of the more scientific amongst you: why has the effect happened to our footprints in the snow?
