The kind of traffic jam where you can stand in the middle of the interstate and take a picture like this:
After we realized we weren't going anywhere in a hurry, Mike and Daniel took a walk, petted a dog, and chatted with a trucker. Meanwhile Benjamin was hungry so I stayed in the car and fed him. Fortunately, traffic started moving again after an hour or so. Mike and Daniel ran back to the car, I strapped Benjamin back in his carseat, and we were on our way once again!
