Don’t mess with a guy on a bike, he might just turn around and put a rock through your window!
That’s what you get for hitting a biker with a bottle, he was not gonna just forget that. He came back with a vengeance and got them good. He hung back and grabbed a rock and came back in hot ready to get the minivan. The driver was lucky he had his window up or he would have just hit him with the rock. The rock must have been tossed with some force to be able to break the glass like that.
