An auction of thousands of items housed inside the decrepit Pontiac Silverdome is back on. The online sell-off had been scheduled to get underway last month but was delayed. RJM Auctions official Jim Passeno said Tuesday that the auction will begin Wednesday and run through June 18-19. The Silverdome is the former home of the NFL's Detroit Lions and the NBA's Detroit Pistons. The 80,000-seat venue north of Detroit has fallen into disrepair, and its current owner is determined to cash in before it's too late. Among the items available are pretzel warmers, a boxing ring, a soccer field, flat-screen televisions and scoreboards.
