Resident Aggie here...
I think this thread is about the bucket list for getting around SEC stadiums and road trips.
I agree with the sentiment someone mentioned above on visiting OU. If you can, I very much recommend the trip!
We don't have a rivalry with OU, so mine is a balanced recommendation here for you coming from experience. I generally judge road trips on: a) whether the opponent has some unique things they do during the game (songs, bands, etc.), b) fan culture / hospitality (at least not be complete jerks), c) gameday campus environment (tailgating, pregame activities), and d) nearby entertainment scene (bars, restaurants, etc.).
Sometimes I go if it's simply an out of conference game that may not come around a lot (e.g., went to Miami last year, though I already knew it would be at the low end or fail much of my criteria).
I'd rate OU pretty high. While they play Boomer Sooner way too much, similar to how Tennessee wears out Rocky Top, it is one of the most recognizable college football tunes and you appreciate hearing it if you are simply a college football fan. Their fans were generally good when visiting us in College Station, and I found them hospitable when we visited Norman. I think it was 2000, when we played a tough game against them in Kyle Field. The #1 Sooners had to rally late to beat us 35-31 in a wildly entertaining game. Though we were disappointed, I recall their fans being complementary of the environment, their experience, and humble walking out, seemingly more excited about seeing an epic game than bent on rubbing it in.
I don't recall their tailgating scene in Norman, so either it isn't as extensive as we tend to have in College Station, or we simply didn't go to the right places, but I imagine it was good based on fan support and behavior. We wanted to go to their entertainment district, which was just across the street from campus, and it was fun for sure - totally felt like a college gameday. Liked it much better than the Austin experience, since Austin is urban, and college football gameday at tailgates in parking garages and such doesn't seem right. I prefer the "college town" gameday experience over urban, OU's is definitely "college town." OU's campus is pretty, they did a good job at making the red brick buildings seem uniform in style.
FWIW - One of the most overrated road trips ever was to Notre Dame. Mainly the awful fan experience walking around campus before the game and in the stadium, and "traditions" wore off quick when you realize what they think of as "traditions" are really just references to "history." It was, however, really cool that their band played the Aggie War Hymn before the game started to welcome us - too bad their fans sitting around us didn't take a queue. I don't plan to go when the Aggies play there again in 2025.
