A few years back I was riding home from Mill Valley, coming down a big hill, when this fool screamed past me in the other lane, then swerved back in front of me and slammed on his brakes for a moment, almost causing me to fall. At the bottom of the hill I caught him in traffic at the light and rolled up on his driver side window and asked him what the hell was going on! He said piss off and screeched away as the light changed. About 2 miles further up the road I spotted his car parked on the other side of the road with no driver in sight, so I rolled over there and covered his windshield with as much phlegm as I could hack up and then proceeded on my merry way home!
