Glad you enjoyed your time here! You're right, there are many miles of fantastic, scenic roads and, best of all, they're nearly all paved. If you get a chance to hit the southwestern part of the state, definitely do it. The roads there wind their way through rolling hills unlike the rest of WI.
The roads right now Nitro whine their way covered with water. Grant county last night got hit hard with over 4" of rain and many roads/homes are flooded in SW WI. I feel fortunate we got only about 2.25-2.5" of rain. Cannot imagine 4" in a few hours or what Milwaukee got which was over 8" that made national news developing a sink hole in the road swallowing an SUV.
TrickyD, how is the WI river in your backyard treating you? I hope it is not up to your patio area outback. Had a flooded basement once back in the mid 90's and don't ever want to go thru that again - what a mess!
