Ames, Iowa, rest area's functional art.
Hwy. 69 was a pretty drive. An Amish wagon had us in tow for
a couple minutes. Since we were on both a curve and approaching
a hill crest, passing was impossible. When he realized we were there,
he politely pulled off onto the grass to let us pass.
Fields were filled with wildflowers. As close as I can determine,
this is checker mallow, but I won't put any money on it.
