I was out riding last night with some friends.We were behind a supermarket where there are several walls and a few loading docks.We were having a good time when one guy hit his chain ring on a wall and screwed it up.We stop to do some repair work when this kid comes around the building in a little car doing about 40mph.I was riding my SS mtb I use for urban riding and my friends were on bmx bikes.I was doing drops into the area that the trucks turn around in.If we were'nt working on my friends bike we may have been smashed.Kids in cars that have no buisness behind the wheel are the ones that bug me.It was scary.
