River Falls to Hortonville, which is the next closest team I don't have in their region is 235 miles and 3 hrs and 36 min away. River Falls to Waunakee is 225 miles and 3 hrs and 25 min.
Superior to Waunakee is 318 miles, 4hrs 39 min., Superior to Hortonville is 310 miles and 4 hours, 43 min.
So I don't see anyway that those potential drives are to be eliminated. If I was in Superior's shoes, yeah I would do what I can to avoid the trip all the way to Madison for round 1. But not much that can be done about the regional they will be in.
By beating Menomonie tonight, Superior probably avoided a long trip in the first round; they are now likely to host that game.
