While we've gotten used to seeing controversial signs driving around town lately, it appears that trend will continue.

But this time, it will involve TRANSPO buses.

A group called the Indiana Atheist Bus Campaign paid for bus ads last week, and TRANSPO announced Monday afternoon that they will be allowing the group to put their ads on the sides of 20 of their buses.

The message on the ad is "You Can Be Good Without God."

The group tried to put their ads on buses in Indianapolis and Bloomington earlier this year, but was rejected.

The ACLU got involved got involved in Bloomington, suing the city over the group's first amendment rights.

The group says they were frankly surprised when they initially found out that their ads were accepted in South Bend; but the decision was actually delayed a week.

Burkhart Advertising, the ad agency TRANSPO uses, accepted the group's payment for their ads last week.

But once TRANSPO found out about the controversy in other cities, it decided to weigh the decision further.

In an executive session Monday afternoon, the board decided to allow the ads. Before announcing the decision, board chairman Chip Lewis quoted President Obama’s commencement speech:

“When we open our hearts and our minds to those who may not think precisely like we do or believe precisely what we believe, that’s when we discover at least the possibility of common ground," Lewis repeated Monday

“We just don’t see anything offensive about it all and we are sorry, truly are sorry, that other groups find that simple statement to be frightening or threatening to their belief system; because we don’t mean to threaten or frighten people,” said Charlie Sitzes, spokesman for the Indiana Atheist Bus Campaign.

“As a result of the controversy TRANSPO is reviewing its policies in regard to bus advertising, to ensure that controversial situations concerning bus advertising may be avoided in the future,” Lewis said.

Lewis says TRANSPO will review its ad policies, and is establishing a 30-day moratorium on non-commercial advertising as it puts together a clear written policy for advertising.

Meantime, the atheist group now says they aren't sure if they want the ads.

Sitzes says they paid for the ads thinking they'd be on buses all last week, leading up to president Obama’s visit. Now, they think the impact may be lost. He says they'll decide what their next move is in a meeting Tuesday afternoon.
