One spring several years ago we had to be careful when talking about three U’s. Son, a U of Wisconsin-Madison student was going to do a summer REU at U of Washington-Seattle while a cousin was going to start at Washington U in St Louis in the fall (an older cousin from the other side of the family had left WI for the WA UW years before and stayed- we learned the U-dub bit from him, that helped). With the two UW’s and two Washingtons it got confusing sometimes. Son was outvoted when he wanted his REU T shirt to have the full name instead of just UW that summer. Granted, it was purple instead of red but no one would realize it meant the other UW back in Wisconsin.
Moved to Tampa a few years ago. USF is here while FSU is in Tallahassee. I find that more confusing than the UF/UFS confusion.
