For Shelby Reinch, it's the first day of her new life.
"I'm just moving in, getting all of my stuff together, said goodbye to my parents," she says.
And as her parents pull away and her roommates settle in around her, they're already making plans as college freshman.
"I'd just like to meet some new people, so I'll probably go to some parties," Reinch explains.
Welcome week parties that every student knows all about.
"It's an opportunity for students to get drunk and get in trouble," MSU Senior Stevon Mosley tells us.
After this weekend's freshman move-in, about 80% of students are now on campus for the year, and Sunday should be the first night those underclassmen will flood the neighborhoods surrounding East Lansing.
The more students the more cops, ELPD and MSU Police have about twice their normal staff load on because they say they know when there aren't classes, students don't have much else to do besides party.
"We've learned from the past that we need a lot of officers to work to make sure things are safe," Sgt. Jeff Murphy of the East Lansing Police Department explains.
Because in years past, the students moving in this weekend have caused the most problems.
"Obviously younger students, being out doing things they shouldn't do," he says.
So for now, police want to make sure freshman like Reinch understand one thing:
"We will be out there and we will be watching," Sgt. Paul Kuchek of the MSU Police Department says.
