Or have you seen deer walking though an early morning mist?

Many times. I grew up on a farm in the country.

I've seen mountain lions and bob cats wander through my yard in the mid morning hours. Deer in the mist, deer in the rain, deer in the snow. A lot of deer actually. I had a small family of them that lived on my back acre. And the moose that moved into my neighborhood for a few weeks. That was awkward.
