I still laugh when few years back when not fully aware to drafting *rules* wouldn't let pass the drafter to take his pulling turn.
Now sometimes we play speed train with the regulars, at one time we drafted a speedy girl for a good half a mile before she freak out to see 4 guys behind her. I am pretty sure she though she had an awesome rear but the truth was that she was imposing a great tempo.
Also there's the “snicky drafter”, competitive in nature but with the obscure intentions to ride in your shade until you show signs of weakness to shot forward in an attempt to drop you, very annoying also.
