Went to the Shoe in 2005, other than the periodic F-you shouted from the out-of-reach passerby I had a good experience but I think my experience was the exception. Also went up there for the OSU-Michigan game in 2018, sat in the "big cigar" section and was shocked by how some of them were talking and acting. They were killing Michigan in the game and the vitriol was flowing ( 50-70 year olds mainly).
I was expecting that the 1998 Nebraska game would be a good parallel for this weekend's Bama crowd. Nebraska fans were very cordial, even in the loss, telling us how glad they were that we got to come up, etc. Great experience overall. That obviously changed dramatically by 2010, where we were greeted less cordially to put it mildly.
BAMA has nothing to prove, they have won 6 titles in 14 years, etc. Certainly, there were several nice people who welcomed us and were very friendly but many more who were obnoxious and way too proud of shouting "horns down" to every person in burnt orange they could spot. My 10 YO was with me and at one point as we are walking over by the ESPN Gameday setup a group shouts "HORNS DOWN" to which I reply with a Hook 'em!! while continuing to walk past them. Then one of them follows with "Hey, Fuck you and your son!" I gave a quick head turn, found who I thought the culprit was, flashed him a Hook 'em and kept walking. My son asked, "why would they do that?" I told him essentially to not worry about what stupid people do or say. Overall, a good trip and wouldn't hesitate to go back for a game but won't have any faulty expectations of cordiality.
Went to Auburn @ LSU in 2013 for a night game, had a great time but was wearing purple and gold. Will plan to go back when UT plays there, hopefully it won't be too bad.
