The skies over Knoxville were quiet for the first time in 29 years this past Labor Day. Last year was the final Boomsday celebration. City leaders said that the summer-ending event was getting too expensive to run and that the city could not bear the burden itself any longer. They claimed the cost for the spectacle was nearly $250,000 and further stated that sponsors no longer wanted to take part. Other attempts at trying to raise money for Boomsday to continue failed.
