UPDATE: 380+ couples get licenses.
The Des Moines Register reports that "at least 261" same-sex couples have applied for marriage licenses in Iowa today:
"The Register is still gathering its data, but afternoon figures show that the greatest number of applications so far is in Polk County, which has logged 82. Johnson County has seen 40 applications so far, Scott County has seen 23, and 22 couples have applied for marriage licenses in Linn County. Today was the first day same-sex couples could since the April 3 Iowa Supreme Court opinion that struck down a state law that said marriage was only between a man and a woman."
