I've taken most of this route several times,
but most of the route south of Glenwood I've taken only a couple times.
Even so, I've enjoyed the curvy and slightly-hilly roads.
The road passes through several small towns where food and gas are
Although the Loess Hills National Scenic Byway
(which actually goes north of Council Bluffs past Sioux City)
ends as the Iowa/Missouri border, SR-275 between the border and Rock Port
is still a nice road for riding.Enjoy!
