2013 KS95 Great Golden Cheese Curd Hunt

It's time once again for the Great Minnesota Get Together,
So gather your Veteran curd hunters and think about a feather.
Once upon a time it was used by the poet, worn by the warrior's son,
That clue should help your idea take flight before this riddle is done.

On the first day of Curd Hunting all around town,
It would behoove you to listen closely for a certain sound.
Because if you're following this poetic trail like a bloodhound,
You wouldn't dare deviate far from the famous Grand Rounds

The poet told the tale of the Big Sea Shores of Gitche Gumee,
But our tiny curd hides on the border of Hennepin County.
In fact, it's near a little white house that gave Minneapolis a name,
But don't hunt in the place where it earned its Ferry Farm Fame.

The next clue is no small joke so just ignore the hecklers,
You know you're getting close when you can hear the laughing waters
