Ha, my wife comes from an Iowa family with a 100% Dutch heritage and your comment rings completely true for me. What's funny is that her family members call themselves cheap and mean it as a complement!
At the same time, there are only two cities in Iowa that have a strong Dutch presence, Orange City and Pella (and both cities have yearly tulip festivals to prove it). As far as demographics go, Iowa is really not much different than Minnesota and Wisconsin--seems to be mostly a mix of German, British, and Irish backgrounds.
Don't let all this Dutch talk make you think that AV needs a Dutch restaurant because I don't think that Pannekoeken Huis restaurant is still in business.
