Some things I've learned about Iowa and/ or Cedar Falls:
1) For many folks, faith/ religion is a very public part of their lives (coming from someone who moved from "secular" Madison, WI)
2) While the climate is the same as Madison, it is noticeably susceptible to hot prairie winds
3) RAGBRAI is a big deal.
4) Having only 3 public universities makes for strong allegiances.
5) Both public education and public radio are strongly supported.
