Snow bunny?

So tell me, what made this strange impression in the snow on my dad's garden path? weird...

fairly crappy day today. managed to get down to my dad's in Reading - 2 hour journey took 4 hours due to very very very slow traffic around Northampton, and my stepmother has missed no opportunity to tell us all how wonderful her children and grandchildren are.

hoping to get down to Dorset to my mum's tomorrow. not sure I'll manage it but will give it a damn good try. need an antidote to the stepmother.
