I know who you guys are talking about. He has a black lab.

It's unfortunate that such incidents ever happen. If they do and the rider doesn't say sorry to involved bystanders, I recommend just apologizing for them. That way, at least we don't all look like we don't care. A similar incident happened at EB yesterday with a kite crashing into a Lexus. The rider said zip after the kite hit and wrapped over the Lexus. Donna ended up apologizing for the person.
