I planned to spend Father's Day filling sandbags. Fortunately the Iowa River floodwaters crested earlier and lower than anticipated and the city told volunteers to take the day off. This was great news for my sore back and even better news for Iowa City. Barring more rain, we've seen the high water mark of the Flood of '08. As the waters recede, it will be time to clean up and calculate the cost of the flood, which may run to billions.
