Everyone I know in Iowa is doing fine and no one's house should be flooded. That said, if I still lived where I lived from grades 2 through 6, I'd pretty much be under water. Most of the route that I used to take to elementary school is a river. University of Iowa buildings where I used to work are being extensively sandbagged in anticipation of the rising waters. This is being spoken about as a 500-year flood.
See Iowa City's Press Citizen newspaper and the Des Moines Register for photos.
Best wishes to everyone in Iowa for a quick end to the flooding and a productive recovery.
