Rapper Ludacris and NFL football quarterback Brady Quinn are among dozens of celebrities converging on Indianapolis for the Indy 500, but the promotion of an after-race party has drawn ire from some.One of three parties being held at the Conrad Hotel will by hosted by Playboy playmates, 6News' Sarah Cornell reported.Indianapolis Downtown Inc. sent a newsletter detailing the parties, including the Playboy event.Attorney and blogger Gary Welsh said he doesn't think it's appropriate for the city to promote a party that exudes sex."I was just a little bit surprised that was an event that they were promoting," Welsh said.Welsh employed his platform at advanceindiana.blogspot.com to decry Indianapolis' involvement.Julia Watson, vice president of IDI, said that as a publicly and privately funded operation, her organization publicizes thousands of downtown events."It would not be within our responsibility to screen anything as long as it's legal and moral," Watson said. "In about three weeks, I think we will have just as much information about the Indy Pride Festival, which is the annual celebration for the gay and lesbian community.""If it wasn't an event that the Hulman George family was putting their blessing on, I don't think that they should have felt obligated to promote that as part of the race weekend festivities," Welsh said.The parties at the Conrad start Friday night and end on Sunday.
