I think Greg Brown's "Iowa Waltz" is a classic. Somebody mentioned it above. I think it's worth posting the lyrics.

IOWA WALTZ
(Greg Brown) © 1981, Brownstreet Music.

Home in the midst of the corn, in the middle of the USA
Here's where I was born, here's where I'm going to stay

(chorus)
Iowa, Iowa, winter spring summer and fall
Come and see, come dance with me to the beautiful Iowa Waltz.

We take care of our old, take care of our young, and make hay while the sun shines
Growing our crops and singing our songs from planting until harvest time.

D Db D G D - A / D Db D G DAD -

(chorus)
