It’s homecoming weekend for students at UMass, and Amherst police say they’ll be cracking down on the partying. On their Facebook page, police posted a behavior reminder to students, starting with keeping the noise down. Excessive noise that disturbs others is illegal, and it includes loud music and yelling. On top of UMass student guest restriction policy enforced this weekend, Amherst police say they’ll be strictly enforcing alcohol laws. The fine for having alcohol in public or having kegs without a permit is $300.
