Minnesota State Mankato students face a big decision today as they vote to approve up to a $10 student fee increase per semester to help fund a new $4 million seasonal sports dome. Students will cast their votes online today. In order for the referendum to pass, 1,100 or more students have to vote and 50 percent of them have to vote in favor of the tuition increase. The proposed sports dome or bubble, which would be located south of Parking Lot 23 just off of Monks Avenue, would consist of three artificial turf fields, each about 75 yards long and 50 yards wide. A seasonal bubble would cover the fields from October 15th to April 14th.
