Thank you both!   
I quote to what I said to my wife at the time “when I am blind, remember this moment”. The sun was literally just popping up and it was directly behind these guys.  I have no idea how this worked.  Through the viewfinder it was awesome, seeing each breath, and I was excited to take the shots.   The deer were on the move crossing, and I was shooting out the drivers side window of my truck. Outside the viewfinder I was staring directly at the sun, and couldn’t see a damn thing and I swear I saw spots for like an hour.    

   A little luck goes a long way.  15 seconds later you wouldn’t even know there was a deer there.
