A few notes. I have been to many campuses and stadiums over the last 40+ years, I will note the ones I thought were nice experiences and those that were over-rated. Others were not really great or bad

By conference:

Big 10: Iowa, Penn State, Maryland, Wisconsin, Nebraska

Michigan - Over rated, this stadium is like a granite quarry with metal benches around the edges. The site lines are horrible, and unlike most stadiums that go "up", this stadium's seating goes "out", such that the further back you go you move much further from the field. In fact you can fit the width of almost two full regulation fields between the edge of the field and the back of the stands. It is ridiculous. The facilities are old and crowded.

Penn State- This is THE loudest venue I've ever attended. The whiteout game vs. Ohio State in 2018 was CRAZY.

Wisconsin- A great venue, not as loud or crazy as Happy Valley, but when they play jump around it is something special. It was also BONE cold and this place was packed and loud.

Nebraska- I have not been to Lincoln since they joined the Big 10, but I was there twice in the 80's and it was a great place, some of the most friendly fans I've experienced as the visiting fan of an arch-rival.

Big 12: OU, Texas, Texas Tech, Okie Lite, TCU

A lot of meh.

OU is a decent venue, I have seen it loud, but recently the fans are lethargic except for Bedlam, that is by far the loudest and most emotionally involved the fans get year to year at home. The new updates and area make it a good place to see a game. I am hoping entry into the SEC will invigorate fans. My experience is that OU travels really well, and its travelling fans are much louder and emotionally involved than the home crowd. I think it is because it has been so long since there was truly an important game played there. The last two games that really got raucous (other than Bedlam) was tOSU and Texas Tech in 2008 when they came into Norman 10-0.

Taco Tech- This place is a HORRIBLE venue, it is small, cramped and the fans are the worst in the Big 12. If you get out of here without having some bit of taco thrown at you, consider yourself lucky.

Texas- like everyone else said, quiet. This is probably a result of the fans experience of 10 years of beatdowns and losses to average and poor teams at home.

SEC: Ole Miss, LSU, Alabama, Auburn, Tennessee, MSU, Vandy,

Ole Miss- Holds sentimental value for me, but it is not a great stadium to watch a game in. The grove and tailgating is a great scene.
State- Sh*thole, which I hear has been renovated into a newer Sh*thole.

Tennessee has to fall in the overrated bin, as has been mentioned, they really pinched pennies to get that capacity, the seats are tiny, such that I found myself bending my shoulders forward the entire time I was seated.

LSU- I've been to three night games in BR, and it is the only scene I think that rivals Penn State. I didn't think it was quite as loud as the white out game I attended, but the tailgating, which begins the night before and continues all night and day to game time makes this a raucous crowd.

PAC: UCLA, Colorado

The Rose Bowl was a huge disappointment. I have been there twice, once in the Rose Bowl game, and the other for a UCLA home game. This place is kind of like the Big House but smaller and not so wide. But it goes "out" in the same way, so there are less good seats that are close to the field. When I was there as an OU fan a few years back, there were quite literally more OU fans there than UCLA fans and this is no exaggeration. It is also old, and the facilities are very dated.

Independents: BYU, Navy, ND

BYU was a great visit. The field is smallish, but the scenery is breathtaking, and the fans are extremely friendly. Was a fun time.

Navy- Anyone who has a chance to go see a Navy game, I'd suggest it for the ceremony alone. Annapolis is a GREAT place to see a game and spend time.

ND- A lot of history, and getting to see the ND band and stuff was pretty cool, but the stadium is "meh". Also, South Bend is "meh" as well.
