He started to get a little weary of only seeing brake lights.
Eventually he did get a little bored, so we found a ball to keep him occupied. It worked well.
Once we got to the lights, he was not as excited as I thought he would be, he fussed, mostly because I was not holding him.
I was taking pictures, and had the window down, so we made him sit in the back, and he was not a fan of not being up in front with us. But, he did get to sit with me up front on the ride home. He promptly snuggled into me and fell asleep.
All in all, it was a pretty good family outing.
