The report found that moving a casino to downtown Indianapolis would capture unmet demand of roughly $350 million within an hour's drive of downtown, more than doubling current casino revenue in that area. The casino would attract Central Indiana residents who won't often drive to inconveniently located sites when they can instead go to a sports game, the symphony or other local entertainment, the report says. The state's top lawmakers aren't convinced Indianapolis needs a casino, despite a new report projecting that a downtown casino would capture hundreds of millions of dollars that existing sites leave on the table.
