Scenery
This is the SE corner of the Driftless, a non-glacial region. Starting off in the farmland around Mt. Horeb, you'd never expect what you are about to see, though it becomes clear the moment you turn off on Fertile Ridge Rd.
It's hilly and windy in the Driftless, with plenty of streams, farms, and fields. Lots of forests to ride through. Seriously, this is the Midwest? With road signs showing squiggly lines and a 30 mph suggested speed?
This area is why I bought a bike.
Drive Enjoyment
Words of warning - there can be a lot of gravel, especially around the apex. There is active farmland, so be on the lookout for drag-on.
The roads, other than debris (which is why I knocked it down one star), are fairly well maintained.
As to the fun bits, it's mostly a combo of high-speed sweepers and low-speed s-curves. There's decent elevation change, especially for the Midwest. The few straight bits simply take you to the next curve.
Be on the lookout for "Rustic Highways." That's usually code for "Freaking Cool Road to Ride." I put on on the ride for your (Marty Rd).
Tourism Opportunities
Beginning and end - 4
Middle - 2
Mt. Horeb has plenty of restaurants and shops, including antiques and places to buy trolls (don't ask me). It's a cute town, though not really my thing. But, hey, there's cheap gas and cold sodas.
New Glarus is really nice. It's a Swiss village transplanted to Wisconsin. Tons of restaurants and hotels. And the brewery (check the hours - they tend to close early) is worth it for a cold Spotted Cow and a gorgeous view.
In between, you can gas up in Blanchardville and Argyle, but don't expect too much more.
