Lou Rosselli Day
On Thursday, January 11, 1996, the Mayor Don Piedmont of Middleport proclaimed "Lou Rosselli Day" in honor of their home grown Olympian as he departed for Atlanta.[7] A banner urging him to "go for the gold" hung above main street, and every shop window held posters wishing him luck.
