REEDSBURG, Wis. -- It started as a way to kick off spring in an area elementary school, but ended with concerned phone calls and a change in school policy.

The controversy over costumes in Reedsburg began after a dress-up day meant to boost classroom energy at the end of winter. But after the response the school got last Friday, the students will have one less theme to choose from, WISC-TV reported.

Looking at pictures of the week, many might think it was Halloween in Reedsburg. Photos show a school filled with poodle-skirted girls and hippie-dressed boys, but the costumes aren't in honor of the haunted holiday.

"Wacky Week has been a tradition for a number of years," said Tammy Hayes, principal of Pineview Elementary School.

This year Wacky Week, where students choose themes for dress-up days, disturbed the peace at Pineview Elementary when its "Senior Citizen and Opposite Gender" day was discovered by a Milwaukee radio group.

"We didn't think about it like that, the kids didn't think about it like that. And therefore, that's why we went with it," said Shari Miller, Student Senate advisor at the school. "We never thought that anything would come about like this."

An area resident contacted Voice of Christian Youth America Radio, who opened the phone lines on their show Friday morning. They said that they believed the day promoted alternative lifestyles.

"If it was some kind of silly party, a birthday or fun, this is not an issue. We're not against kids having fun," said Vic Eliason, vice president and executive director of VCY America. "But one of the things that has happened of late is the issue of gender and transgenderism, and these are deeply held issues within the family."

District officials took action and said while Wacky Week will continue, opposite gender day won't.

"We did not mean to offend anybody by accepting the children's idea here and the children certainly did not mean any ill will by choosing this day," said Hayes.

"I commend them for being responsive," said Eliason. "I think they took a good step. They did what was right."

The radio organization said their lines were jammed when they discussed the issue Friday, and many of those phone calls rolled over to the school district. Both the administration and the school received numerous calls over the past few days, WISC-TV reported.
