Forget CDs. Don Radke, proprietor of Don's Discs, has more used records than he has time to clean, sort and stock. He stopped keeping count years ago, but Radke figures that more than a million separate slabs of vinyl inhabit his increasingly cluttered space in Thornton. While many a local has bought and sold his record collection here since the doors opened in 1982, Don's has garnered something of an international reputation in the time since, so it's not uncommon for European and Asian record fetishists to come to town and clog the shop's aisles for days at a time.
