I'm flying to Minneapolis in 3 weeks. I've never been there. I will be in the area for 5 days. We'd like to take a day or two and also drive into WI and maybe up to Canada (just to cross the border and use our passports). I have 2 kids (older elementary school aged) and we'd like some suggestions on fun things to see and do. We're excited to get a little respite from the Texas heat. Thanks for any info!
