What? You WANT a diagram? OK, don't say I never did anything for you. (This will prove what a big nerd I am, I actually made this and had FUN doing it too.)

A few hundred cars will fit in the holding area after the toll booths and the line can stretch for many many many many many blocks before you even reach the point where they empty your wallet. I've been stuck in that line-up for over 2 hours on busy days, which is why I always bring a book or knitting with me.
