As the snow and ice start melting away, downtown boosters are hoping to keep springtime streets clear of manmade litter, said Linda Holterhoff, executive director of Keep Cincinnati Beautiful.

She said KCB is kicking off its "Don't Trash the 'Nati-Keep Cincinnati Beautiful" public awareness campaign. During the campaign, KCB will display its award-winning billboard sign: "Don't Trash the 'Nati."

This year, the campaign will try a little parody, using a basketball theme to emphasize awareness of keeping the inner city clean.

One display is a sign, labeled "Score," which shows a trash can connected by a dotted line to trash lying nearby. "The point here is to remind people that everyone wins when we put trash in its proper place," Holterhoff said.

Another sign is labeled "It ain't no game." It shows a close-up of a broken bottle on a basketball court. Holterhoff said the ads target teens and young adults, which research has shown is the age group most likely to litter.
