Probably the campus squirrel hunting.
But seriously, for a state with one of the lower percentage of black residences in the country, the University of Iowa has an outlandish tradition in welcoming minorities.
First woman in the entire nation to earn a law degree - 1873
G. Alexander Clark - first black in the United States to earn a law degree - 1879
Believed to be the first black varsity athlete ever - Frank Holbrook 1895
The first black All-American football player Duke Slater - 1921
The first black NCAA wrestling champion - Simon Roberts 1956
The University of Iowa is not perfect, but the school tradition for welcoming blacks and minorities is well know - at least in Iowa. But then again, wrestlers hunting rabbits and squirrels on campus is the quick take I guess.
