The following day I toured the south loop.
Here, oncoming traffic was stopped. I cut across to the turnout that was on the other side of the road. I was the first one to do so and was able to pull right to the front of the area. I saw the herd was making it's way towards me so I just sat in my car and read as they approached, taking the occasional picture. Once they go closer, I stepped out and took a few pictures.
