If Kansas defeats Maryland and you’re celebrating on Massachusetts Street this weekend, be aware: Glass bottles aren’t allowed, and security cameras may be on you.

An Elite Eight appearance would trigger a ban on glass bottles and other beverage containers on downtown streets and sidewalks. The ban will run from noon Saturday to 6 a.m. Monday. If caught with glass, violators face a misdemeanor punishable by a fine of up to $100.

The Lawrence Police Department announced via its Twitter account Tuesday that officers would be visiting downtown businesses this week, requesting they serve drinks in plastic.

Your celebrations may also be on security footage.

Though the LPD does not use downtown security cameras year-round, they are placed there temporarily to manage and oversee NCAA celebrations.
