Of course what my wife said was more like "Oh my God its a bear!!" at a rather high volume. Not a great pic, but I was a bit concerned myself. He was also about 8 feet from the sliding screen door on the patio on that side of the house.
If he had wound up inside that would have been a real adventure.
After I snapped a quick picture, he wandered away, likely down to the river for a drink.
