Like a dueling dragster, the man who operates Spokane Raceway Park is squaring off with disgruntled investors who say they haven't seen any return on $2.5 million in stock they bought 30 years ago. Orville Moe, a crusty, gun-toting 67-year-old millionaire, says that the power struggle is being inflamed by estranged family members and that he's done nothing illegal. But the Spokane business legend could face state and federal investigations, and he has been named in at least two lawsuits, including one brought by the Kalispel Indian Tribe.
