I am waiting for the Suck-Eye fans to go on about their stadium experience
But now that we're on it, I would have to say FLA's isn't that awesome. Yes, it's 90k+ people (noted below the 100k of several Big10+2 schools) and the structure is shaped more to hold the sound in and make it deafening (FL-FSU was one of the most intense experiences of my life, seriously), but all in all it's kinda 'meh' in my mind. Admittedly, I grew up going when the stadium was empty, and watched several additions to increase capacity and size, and having been there for 30 yrs, one becomes oblivious to the grandness of things to the point of perhaps taking them for granted. But even with the tailgating, the recent addition of the Gator Walk (players thru the fans), and all the bars so close to the stadium....it's still a pretty 'meh' experience.
Now, for a country bumpkin redneck - yeah, it might be impressive; especially the energy and enthusiasm of the fans. But for a real college fan, with experience in other stadiums, I don't think I'd put UF on your list of places you need to visit. Neyland? Maybe. Horseshoe? Maybe, probably (been there, but it was closed

and not a gameday). Big House in Ann Arbor? Maybe, probably (been there, walked the field, not a gameday).
Actually, running down the SEC stadiums in my mind:
FLA - no
UGA - maybe, no.
KY - no.
USCe - no (though, I **HIGHLY** recommend eating at "California Dreaming" if you do go

).
Vandy - hell no
TN - maybe, probably
JAX - for FLA vs UGA, hell yes.
--
AL - probably, but I don't have much basis for my opinion
AU - hell no (buddies went once, there is *nothing* there)
MISS - no
MSU - no (needs less cowbell)
LSU - Yes (again, history and food sway my opinion here)
ARK - no (no basis for opinion)
Others?
USCw - probably, for the history of the location as much as the program (and to cheer for the other team

)
Penn State - probably, for the history (and my wife is insistent we have to go at some point

This Florida boy is not interested in freezing his ass off

)
Cotton Bowl - TX vs OU, absolutely would love to, especially as it ties with the state fair (why is food so important to me?)
NEB - probably, for the history, and to see if there is anything there besides cornfields
..... I think that's about all of them I'd recommend/want-to-see.
