Unwelcome visitors

Twice in the same week !

First, about 3 days ago, I see this one crawing ACROSS MY FRONT YARD !   I follow him, videotaping on my phone, and he disappears underneath my back deck.

Then, today, while attempting to transplant a few volunteer Blackeyed Susans, I nearly step on this one.  He was lying just over my boundary line in the backyard of the next door (unoccupied) property.

I don't know if this is two separate snakes, or the same snake seen twice, but I'm not loving it !
