I do not understand the "thread" title either.
The final 4 are as follows:
OU
UNC
Nova and
Syracuse
Syracuse is definitely yankees since they are in New York
UNC is a Johnny Reb state
OU wasn't even a territory then
Nova (from Philly) would be classified as a yankee state.
So that is 2-1-1
But y'all should do a little history reading regarding Philadelphia, the state of Maryland, and the mason dixon line. It could be considered a southern city. And you will learn something. It is very interesting
