Cruising along headed home in Menlo Park. Happened upon these Harley riders. Thought they were chill because they were bumbling along slowly. As I slowly passed them, they gunned it. Thought it would received as good natured fun in this nice part of town. Boy was I wrong. They got really really pissed. Blocked my path. And had a few choice words! What a surprise. I now know better. (dash cam clip below, sorry for the audio in the 2nd part -seems corrupted).
