If you're going through Keokuk, you ought to nip over to Nauvoo.
I remember Nauvoo in the 50s as a small little town. The various homes
were dilapidated and weed covered with a small sign indicating it was the
home of someone. The last time I was there was maybe 1982 and a lot had
changed, the weeds were gone and many houses restored. I was thinking of
looking the place over again. I know a lot of Mormon history so it would
be interesting where they have gussied it up more.
I also found a place in Ft Madison that may have a part I need for a tool
so that seems to have solidified my route.
