If you stuck around after that first car nearly killed you then you deserved to get creamed by the second car. Actually if you lined the track with your parked car you deserved to die driving to the event.
A simple flag marshalling system, (like in track events) would work instead of marshalls just blowing whistles when cars were approaching. There should be some feedback to the drivers. Well that was my sensible head talking..... I blame the Amish.
In addition to plain text you can also add links to: - images - video pages - anything else Simply add a link just like this: http://i.imgur.com/fhfnG.gif and we will do the rest. We will transform all links into clickable links and if the link points to an image or a youtube video page we will open that image / video in a clean pop.
