Public ranges near New Ulm, MN

My wife's side of the family is having a reunion this summer in New Ulm, MN and one of her cousins has asked if I wanted to set up some time to do some shooting. So, is anyone here familiar with the area by chance? Are there any decent outdoor ranges within 30ish minutes? Preferably a free public range. From Google maps it looks like New Ulm is about 1 hr 45 min SW of Minneapolis or 35 minutes WNW of Mankato for reference. Any help would be appreciated! Thanks!
