There are potential "fun" bars/restaurants near almost any college campus in the whole country, but...Is Stillwater or Lubbock as fun as Tempe or Seattle? Lol ..of course not but road trips shouldn't be the #1 reason to be in a conference. BTW I've heard there are some fun bars/restaurants near Okie St.
As for BIG 12 roadies... I'd go to Morgantown, Cincinnati, Orlando. I hear KU has a pretty campus.
Orlando is a ****hole with a theme park.
Morgantown is a crumbling campus surrounded by poverty and meth.
Cinci is worth a visit. Once.
Lawrence, Stoolwater, Ames, Manhattan, Lubbock, and Waco are all ****holes.
Houston has some world class restaurants and bars.
DFW is DFW with all of its pros and mostly minuses.
Provo could be nice, but it's basically Boulder with even less diversity and no alcohol.
What's key there is that with the exception of visiting a theme park that happens to be located in one of those locations, none of those are locations you would go to absent a compelling reason to do so.
OTOH,
Many of the locations in the Pac are places where people choose to visit just for the enjoyment of visiting the area. It's definitely a plus.
The B1G also suffers from ****ty location problems, but at least it compensates with actual quality football tradition.
