The Pontiac Silverdome, once home to the NFL?s Detroit Lions and NBA's Detroit Pistons, was sold for $583,000, or about 1 percent of the $55.7 million it took to build in 1975. The Silverdome is an 80,300-seat stadium located in Pontiac, Michigan. ?It?s certainly one of the most severe points in [the area?s] history, because of the economic crisis and the falling housing prices,? says Mark Skidmore, professor of economics at Michigan State University in East Lansing. ?There?s been a massive exodus and the ones who are left are those who, by and large, are [lower] income.? The Silverdome was considered to be worth $20 million as recently as last year and at least $3 million now. An Oakland County judge has halted the sale until at least Monday. A rival buyer filed an injunction to block the sale. The city of Pontiac now owns the stadium and is keen to offload it because of high maintenance costs.
