I'd be very interested to know what the demographic breakdown is of fans who attend our games (what % are from Broward, Dade, Palm Beach, elsewhere in FL, out of state, etc). I also think that as Broward has become much more of a major player in high school football and producing P5 talent over the last 20 years or so, it can't hurt us to have a major presence there.
This is never going to be an easy answer because there's not going to be an on-campus stadium and some segment of the fanbase is going to bytch and complain regardless of where we play. But one thing I don't think any of us can disagree about is that, location aside, we unequivocally will not play in a nicer stadium with nicer amenities and all the trimmings outside of Hard Rock Stadium. And when we are winning and the stadium is packed, I can't think of a better realistic option.
EDIT: I know the stadium is not in Broward, but it's practically on the border of Dade and Broward and very convenient for Broward and Palm Beach folks to get to.
