The National Rifle Association will hold its annual meeting in Indianapolis.
The April gathering is expected to draw about 65,000 NRA members.
VisitIndy spokesperson Chris Gahl says the NRA signed the deal in 2010 and announced it to its members, but asked Indy‘s convention bookers to hold off on publicizing the event.
He says the NRA convention could be the biggest of the year for Indianapolis, with an estimated economic impact of $55-million.
The meeting will draw 700 exhibitors selling a variety of firearms, as well as hunting, camping and other outdoor gear.
It will also feature speakers and other entertainment, which Gahl says will be announced at a later date.
