KANSAS CITY, Mo. -- Along with street closings, many drivers will also see emergency no-parking signs along busy downtown streets.

Buses filled with hundreds of kids are bringing the students to the National Catholic Youth Conference at the Sprint Center. The buses are parking in the Crossroads District to unload students to walk to the conference.

The no-parking ordinance being enforced this weekend is unpopular with the small businesses in the Crossroads District who are being affected. Several business owners said the city put the signs up at the last minute without much warning and began ticketing and towing their customers' cars.

The owners feel there are other places that the city could have used to park the buses.

"That negatively impacts a lot of us small businesses in the Crossroads District that are trying to stay alive," said Sherri Parr, the owner of The Brick bar.

"Why was it slated to come into the east Crossroads in the first place when we have the Kemper Arena or Science City, where they could've parked these buses?" said Grinders owner Anton Kotar. "There are people who do business here."

More than 22,000 kids are in town for the weekend from all over the country for the conference and it is expected to pump more than $15 million into the local economy.
