Pro Tip: If you want to fight a dirt bike rider, make sure they're not wearing their gear. One driver fed up with a dirt bike riding near his car, got out of his vehicle and started swinging at the biker. The biker was nonplussed at the attack but quickly got defensive. Given that the biker was in full gear, he was unharmed, though the same cannot be said for the attacker.
And a domestic dispute ended in a hit & run when the woman involved in the fight hit her partner with her car. The man was on a bike when he was hit and was taken to the hospital with head and back injuries.
