The few blacks who came to Oregon to attend school are definitely a minority.  Times change, though.

When I was at Duck U Law School, there were only four women law students; now it's 206 male and 160 female. 

There were no blacks then; now there are 9.  And total minority is 67. out of the 366 total.  

The only other minority I recall when I was there was a guy who was Native American and he had already served as an Officer in a submarine and was also a CPA, so he kinda stood out!
