The metal will crunch, tires will blow and the crowd will be on the edge of their seats. The 2007 Carbon County Fair will again be hosting two evenings of demolition derby events in August. These events promise to be as exciting as last year's event. There will be a new format and new management to the events this year.
On Thursday, August 9th, the first derby event will be a figure 8 race; consisting of three heats and a feature. This will be followed by a second event featuring a small car demolition derby feature.
