Shoe Prints in the Snow

What do I find so strange about the shoe prints I saw in the snow in front of my house?  A few things.  First, no one was there.  The road was closed for several days.  There were no UPS or FedEx deliveries.  There was no mail delivery.   David came by after around three days because I asked for help with an issue out in the driveway, but he drove here and has all weather tires on his truck, and only attempted to drive over after a lot of the snow had melted.   I saw his boot prints out near the road.  But these were not the prints I saw in front of the house.  

Other than David, no one was here for any reason for a few days because of the snow from the storm.  And yet there were shoe prints that weren't mine or David's.  This startled me when I noticed it, because no one had been here.  No one had any way of getting here.  

Then there was the shape of the prints.  I have seen the prints from this same shoe in the past.  The weird thing is, I see these prints every time it snows.  I have written about it before.  The prints are what I would call about a size nine or ten.  Not especially large, but not small.  About the size of my foot.  I have thought of cowboy boots when I see them.  They always have pointed toes and a slick sole.  

I'm hallucinating, I thought.  I didn't see those shoe prints again.  I had almost convinced myself of this, when I saw them again this morning behind my car in the remnants of the snow.  But could these be my shoe prints?  No way.  I have shoes that might make a similar print, but not at this house, and I haven't worn them in a while.  Besides that, I hadn't walked out in the snow except once, and it wasn't in the same location.  I was actually wearing flip flops on my one walk.  

I can't think of a good explanation for these eerie prints.  It has been suggested to me that I put surveillance cameras around so I can see what's going on around the house outside.  Well, maybe.  I'm actually a little bit afraid of what would turn up.
