Mountain Lion sighting in Portland, Ct

On Tuesday, July 29th at around 5:00am I looked out my bedroom window and a very large animal was lying down on Glastonbury Tpke/Rt 17. We live across from a wooded area and close to an outlet of the CT. River. Thinking it was an animal that was hit, I watched it. Then I could see the head move and it was just looking around content where it was. We have a street light in front of the house so I had a good view. I turned on the porch light and opened the front door and it just looks at me and was not afraid. I then opened the screen door and it bounded to the side of the road and I could see the side of view of this animal. Long, lanky, light in color and a very long tail. When it was looking at me it had the face of a mountain lion with rounded ears. I have no doubt that is what I saw.
