knees36: Yep, crooked roads in Iowa usually means hilly roads or following a river bank, BUT beware, a straight road doesn’t always mean flat terrain, especially in southwsstern Iowa. I driven and ridden (a bicycle) over such roads like County Roads E16 from Mapleton to Breda, #F24 through Irwin, #M47 again through Irwin, #M66 from Manning south to Kimballton and many other roads like these in Harrison, Audubon, Shelby, Crawford, and other counties in this part of Iowa. Not exactly like Potter’s Hill, but still nasty/exhilirating hills. The fastest downhill I’ve ridden anywhere in the USA is in my old home county, Harrison, at 50+ mph on #F32, in the heart of the Loess Hills.
Fifty? Wow, never been that fast. But then again, I guess the pavement feels the same whether you’re doing 30 or 50 huh? lol
