I just looked at this thread and realized where and when this event is. I haven't been that far north in a while and have never been up there in a bike...I'm in! Now to see if anyone else is going from Indiana or passing through. Looks like I can slab it to Quad Cities on I-74 or take Hwy 136 to Danville, IL then Hwy 150 through IL to Quad Cities, or?
I'd shoot up north and west via slab or 2-laner of your choice to west of Rockford and amble back roads to Dodgeville...the roads from there get pretty fun. I'm sure the N. Illinois contingent will give an assist.
Where in "midwest" are you located?
Mayberry.
Also known as Wheaton, IL...
...but that address may change this spring or summer. I may be relocating south and east of the Smokies this year, if I am successful in my new job search.
So I may have to travel farther to NAFO...but I will still know that back way to get there.
