Janesville would be useful to me for trips between Minneapolis and Chicago; since my SR+ can get the Tomah to Menomonie run in cold weather, Mauston to Janesville should be doable as well. During warmer months, I would probably be able to set it up home to Menomonie to Tomah to Janesville to at least Rolling Meadows. In September, I got Rockford to Rolling Prairie, IN, on the Indiana Toll Road, which leads me to think that Janesville to the westernmost service areas on the Indiana Toll Road is likely doable, too.
