So...maybe 'draft' is the wrong word.
But I'm pretty sure that someone can be behind a slow-moving tractor trailer (ie: 60 in a 65) in the right lane, follow at a safe distance, and still be able to benefit from the wind break.
And because this particular truck was going below the speed limit, even with space in front of me, no sane person would jump between me and him, since he was so pokey.
I read the 101 tips after I posted this, and noticed the 'no drafting' policy, so if I upset the apple cart, I apologize.
