Puzzling

While I was gone yesterday afternoon, there was one set of fresh footprints in and out of my place. No note, nothing left, doesn't look like anything missing. Anyone who knows me, would expect that if the truck isn't there, I am not home.

A few weeks back, a couple (with dog in vehicle) stopped at another home on my street, and the comments made to the dog, that were overheard, would indicate that the people do not know who lives there. 

There have been door to door JW visits up here in the past, but they were asked not to come back to my house.

If you had someone at your door yesterday, or know who it might be, I'd appreciate the info.

I will be making camera adjustments, but I would like to know who was here.
