Whenever you are driving on a two lane highway and there are two eighteen wheeler trailer trucks blocking both lanes and driving ten miles below the speed limit which causes a significant amount of traffic.
I was making great time driving on Highway 70 on my way to Kansas City, but then there was a huge cluster truck.
