For many people, homecoming started long before Friday night's parade.
There were a ton of events happening on campus all week, from hay rides to craft night to an ice cream social with Sparty himself.
There's something very special about homecoming for current students and alumni.
"Brings back a lot of memories," Mike Shaft said.
Shaft graduated from MSU in 1968. He came back this year to visit the Surplus Store with one goal in mind: buy a brick from the remains of Morrill Hall, the century-old building, demolished earlier this year
"I took classes there at Michigan State, so I had to get a brick for the memory, and a piece of history for the MSU campus," Shaft said.
He wasn't alone. The bricks went on sale Friday morning, and they were selling like hotcakes. The MSU alumni association isn't surprised. They said homecoming is the largest gathering of Spartans in East Lansing each year.
"The energy that's going on here with all the alumni in town is so infinite that you could literally power the city of Lansing for a year," Vice President of Alumni Relations Scott Westerman said. "They're a lot of people that come and don't even have tickets to this game, just because they want to get together with the people that were so important to them while they were Spartans here."
Of course, current students are excited, too, especially freshmen just trying to soak it all in.
"Homecoming week is like super exciting," freshman Julie Dunmire said. "I don't really know what to expect, because this is my first year, and I'm excited to see what's going on."
She enjoyed free MSU Dairy Store ice cream and a visit from Sparty at the rock on campus Friday, where many others celebrated homecoming and a 20th birthday.
"It's perfect that my birthday is today and it's Friday, and it's homecoming weekend, it all kind of aligned perfectly," Evan Lewandowski said.
Now they just hope it all aligns for a victory on Saturday, but win or lose, it's always good to be back in East Lansing.
"It's a great atmosphere, it just never loses it's touch at MSU," Shaft said.
The bricks from Morrill Hall are $35 each and can be purchased at the Surplus Store or online.
Homecoming game kick off against Indiana is set for 12:00 noon.
