Current plan is to fly into the Twin Cities, rent a car, drive to Marshfield to hang with some high school buddies and then head North to Boulder Junction.
I will have my wife and kids with me. Best part is my son will be 8 and is super excited to play a few new courses.
Well. If driving over from the twin cities, you would pass right through my backyard. I'm only 7 minutes off of 94. If you're interested in bagging a few courses along your drive, there are a few courses in Menomonie that are pretty decent and wouldn't be out of your way more than a few minutes. Wakanda park is a decent (although somewhat unspectacular) course that is also a big city park, big playground and small animal park (buffalo and elk) that would make a decent stop traveling with family.
Bonus is that the front 9 ends at the playground of the little guy is getting bored of disc. That's usually where I lose my son lol.
Menomonie middle school has an 18 that's pretty nice, fairly short, and a quick play. My son and I play that one often.
Brickyard is also a really neat and very well done 9er.
Eau Claire WI has the tower ridge courses which are super fun, but a slog with the little one with.
Over towards Marshfield, there are a few awesome courses. Wolfhaley should be able to fill you in better on the ones over that way. I've only ever played Big Eau Pleine over that way, but that was one of my favorite courses I've played.
Up north though, the answer is Highbridge Hills, without a doubt.
