2 things:
On my way to work the other morning, in a 3 lane highway on the far right lane was a tractor/trailor moving some large cargo. A motorcycle cop was in the lane directly left of it (the middle lane) with flashing lights. This is common when moving large stuff. The idiot in the left hand lane refused to pass the cop to her inside. We were going about 35 mph down I-10. Must have been 200 cars backed up behind her. IF there was a such thing as God He would have ordered a meteor to land on this person's car. I had visions of owning a monster truck and running over this idiot.
Next, boat ramps. There is not a more target rich environment if you are looking for dolts. When I get a little insecure about skills or abilities required to make it thru life, I just go to the boat ramp and give myself a pep-talk. If these mental midgets can survive then I won't have a problem.
