Ryan, I hope you'll forgive me when I came across from Twitter to read this, I had no expectations it would be much good, but I thought it might be an interesting insight into an industry I know nothing about. I assume you love your job because the degree of intelligence exhibited here, the clarity of explanation and the simplicity in which you've made a very complex subject seem so easy to understand is amazing. Seems to me, your'e wasted as a truckie, and a few university professors I know personally, would have had a much harder job explaining this in a way that lay people like myself can understand. I suspect, this will go viral, I certainly hope the people who need to read it will read it - great job
