It's a new event called YMCA Madness.
You make your bracket picks at the Y for $5.
Whoever wins gets their name put on this basketball trophy - which will remain at the YMCA for years to come.
All of the money raised will go toward the facility's Healthy Kids Day next month.
I think that would be great if we could get the people involved now, Philly that day can be a very successful day for all of the kids in the community," said LaJoya Smith, aquatics director at the Vigo County YMCA.
Ryan Daffer, the Y's community wellness coordinator - and who came up with the YMCA Madness idea - adds: "Already, the buzz that's been generated is just great. People are interested, they want to know more about it... How did they get their name on that trophy. You know everybody's got their winners predicted already and it's just day one so exciting to see."
You don't have to be a member of the Y to take part.
Just have your bracket and $5 turned in to the Vigo County YMCA by Thursday.
