No judgement, I suspect many do.
We Have University of Florida (HCBW's grandfather worked there many years,) University of Pennsylvania (HCBW's brother was their kicker) USF (South Florida, HCBW's sister went there) UVU (Local school. Former BIL who is still like family works there.)
BYU is our number 1 and we rep the Y more than anywhere else, but see plenty of valid reasons to rep other schools occasionally.
